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 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<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 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.
