Enum Context 

pub enum Context {
    Default,
    Custom(CustomContext),
}

A context within a [Purpose] for more fine-grained verifier assignments.

An example for context is the name of a specific software repository when certificates are used in the context of the packages purpose (e.g. “core”).

If no specific context is required, Context::Default must be used.

See https://uapi-group.org/specifications/specs/file_hierarchy_for_the_verification_of_os_artifacts/#context

Variants

Default

The default context.

Custom(CustomContext)

Defines a custom Context for verifiers within an [Os] and [Purpose].

Implementations

impl Context

pub fn parser(input: &mut &str) -> Result<Context, ErrMode<ContextError>>

Recognizes a Context in a string slice.

Consumes all of its input.

Errors

Returns an error if

• input does not contain a variant of Context,
• or one of the characters in input is not covered by IdentifierString::valid_chars.

Examples

use voa_core::identifiers::{Context, CustomContext};
use winnow::Parser;

assert_eq!(Context::parser.parse("default")?, Context::Default);
assert_eq!(
    Context::parser.parse("test")?,
    Context::Custom(CustomContext::new("test".parse()?))
);

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Context

fn deserialize<__D>( __deserializer: __D, ) -> Result<Context, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'_derivative_strum> From<&'_derivative_strum Context> for &'static str

fn from(x: &'_derivative_strum Context) -> &'static str

Converts to this type from the input type.

impl From<Context> for &'static str

fn from(x: Context) -> &'static str

Converts to this type from the input type.

impl From<Context> for ConfigContext

fn from(value: Context) -> Self

Converts to this type from the input type.

impl From<CustomContext> for Context

fn from(val: CustomContext) -> Context

Converts to this type from the input type.

impl FromStr for Context

fn from_str(s: &str) -> Result<Context, <Context as FromStr>::Err>

Creates a Context from a string slice.

Note

Delegates to Context::parser.

Errors

Returns an error if Context::parser fails.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for Context

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Context

fn cmp(&self, other: &Context) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Context

fn eq(&self, other: &Context) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Context

fn partial_cmp(&self, other: &Context) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Context

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Context
