impl<'t> EntityTag<'t>

pub fn with_string<S: AsRef<str> + Into<String>>(
    weak: bool,
    tag: S
) -> Result<EntityTag<'static>, EntityTagError>

Construct a new EntityTag.

    weak: bool,
    tag: &'t S
) -> Result<Self, EntityTagError>

Construct a new EntityTag.

impl<'t> EntityTag<'t>

pub fn from_string<S: AsRef<str> + Into<String>>(
    etag: S
) -> Result<EntityTag<'static>, EntityTagError>

Parse and construct a new EntityTag from a String.

pub fn from_str<S: ?Sized + AsRef<str>>(
    etag: &'t S
) -> Result<Self, EntityTagError>

pub fn from_data<S: ?Sized + AsRef<[u8]>>(data: &S) -> EntityTag<'static>

Construct a strong EntityTag.

pub fn from_file_meta(metadata: &Metadata) -> EntityTag<'static>

impl<'t> EntityTag<'t>

pub fn get_tag(&'t self) -> &'t str

Get the tag. The double quotes are not included.

pub fn into_tag(self) -> Cow<'t, str>

Into the tag. The double quotes are not included.

impl<'t> EntityTag<'t>

pub fn strong_eq<'v>(&self, other: &EntityTag<'v>) -> bool

For strong comparison two entity-tags are equivalent if both are not weak and their opaque-tags match character-by-character.

pub fn weak_eq<'v>(&self, other: &EntityTag<'v>) -> bool

For weak comparison two entity-tags are equivalent if their opaque-tags match character-by-character, regardless of either or both being tagged as “weak”.

pub fn strong_ne<'v>(&self, other: &EntityTag<'v>) -> bool

The inverse of strong_eq.

pub fn weak_ne<'v>(&self, other: &EntityTag<'v>) -> bool

The inverse of weak_eq.
