Enum PseudoHeader

#[non_exhaustive]
pub enum PseudoHeader {
    RequestTarget,
    Created,
    Expires,
}

Pseudo-headers are used to incorporate additional information into a HTTP signature for which there is no corresponding HTTP header.

They are described as “special headers” in the draft specification: https://tools.ietf.org/id/draft-cavage-http-signatures-12.html#canonicalization

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RequestTarget

The (request-target) pseudo-header is constructed by joining the lower-cased request method (get, post, etc.) and the request path (/some/page?foo=1) with a single space character.

For example: get /index.html

Created

Passed as part of the auth header

Expires

Passed as part of the auth header

Implementations

impl PseudoHeader

pub fn as_str(&self) -> &str

Returns the string representation of the pseudo-header.

Trait Implementations

impl Clone for PseudoHeader

fn clone(&self) -> PseudoHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PseudoHeader

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

Formats the value using the given formatter.

impl From<PseudoHeader> for Header

fn from(other: PseudoHeader) -> Self

Converts to this type from the input type.

impl FromStr for PseudoHeader

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<PseudoHeader, Self::Err>

Parses a string s to return a value of this type.

impl Ord for PseudoHeader

fn cmp(&self, other: &PseudoHeader) -> 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 PseudoHeader

fn eq(&self, other: &PseudoHeader) -> 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 PseudoHeader

fn partial_cmp(&self, other: &PseudoHeader) -> 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.
