Struct ETag 

pub struct ETag {
    pub value: String,
    pub weak: bool,
}

An HTTP ETag header value, either strong or weak.

Fields

value: String

The opaque tag value (without surrounding quotes or W/ prefix).

weak: bool

true if this is a weak ETag (W/"…").

Implementations

impl ETag

pub fn from_bytes(data: &[u8]) -> Self

Creates a strong ETag whose value is the FNV-1a 64-bit hash of data.

pub fn from_str_value(s: &str) -> Self

Creates a strong ETag with an explicit string value.

pub fn weak(value: impl Into<String>) -> Self

Creates a weak ETag with the given value.

pub fn to_header_value(&self) -> String

Formats the ETag as an HTTP header value: "value" or W/"value".

pub fn parse(s: &str) -> Result<Self, CacheError>

Parses an ETag from an HTTP header value.

Accepts "value" (strong) and W/"value" (weak).

Errors

Returns CacheError::InvalidETag if the string is not a valid ETag.

Trait Implementations

impl Clone for ETag

fn clone(&self) -> ETag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ETag

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

Formats the value using the given formatter.

impl PartialEq for ETag

fn eq(&self, other: &ETag) -> 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.
