Struct Fields 

pub struct Fields { /* private fields */ }

Raw ordered pairs. Duplicate names, spelling, spacing, and opaque value bytes are preserved. Interpretation belongs to an explicit header policy; trailers are a separate BodyFrame::Headers event.

Implementations

impl Fields

pub fn new() -> Self

pub fn with_capacity(capacity: usize) -> Self

Fields with storage for capacity pairs, for a driver that knows how many it will add.

pub fn reserve(&mut self, additional: usize)

Reserve storage for at least additional more pairs.

pub fn try_from_pairs<N: AsRef<str>, V: AsRef<[u8]>>( pairs: impl IntoIterator<Item = (N, V)>, ) -> Result<Self, FieldError>

pub fn pairs(&self) -> &[Field]

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn values<'a>( &'a self, name: &'a str, ) -> impl Iterator<Item = &'a [u8]> + 'a

pub fn contains(&self, name: &str) -> bool

pub fn add( &mut self, name: impl AsRef<str>, value: impl AsRef<[u8]>, ) -> Result<(), FieldError>

pub fn append(&mut self, field: Field) -> Result<(), FieldError>

pub fn set( &mut self, name: impl AsRef<str>, value: impl AsRef<[u8]>, ) -> Result<(), FieldError>

pub fn remove(&mut self, name: &str) -> usize

pub fn retain(&mut self, keep: impl FnMut(&Field) -> bool)
