Struct miltr_common::modifications::headers::ChangeHeader

pub struct ChangeHeader { /* private fields */ }

Change an existing header

Implementations

impl ChangeHeader

pub fn new(index: u32, name: &[u8], value: &[u8]) -> Self

Create a Header from some bytes

pub fn name(&self) -> Cow<'_, str>

The name of the header

pub fn value(&self) -> Cow<'_, str>

The value of the header

pub fn index(&self) -> u32

The index in a list of headers sharing name which to change

Headers can be set multiple times. This index is only valid in the context of headers with the same name.

Trait Implementations

impl Clone for ChangeHeader

fn clone(&self) -> ChangeHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeHeader

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

Formats the value using the given formatter.

impl From<ChangeHeader> for ModificationAction

fn from(v: ChangeHeader) -> ModificationAction

Converts to this type from the input type.

impl From<ChangeHeader> for ServerCommand

fn from(value: ChangeHeader) -> Self

Converts to this type from the input type.

impl TryInto<ChangeHeader> for ModificationAction

type Error = &'static str

The type returned in the event of a conversion error.

fn try_into( self ) -> Result<ChangeHeader, <Self as TryInto<ChangeHeader>>::Error>

Performs the conversion.

impl Writable for ChangeHeader

fn write(&self, buffer: &mut BytesMut)

index : uint32 is Index of the occurrence of this header. index has to > 0. (Note that the “index” above is per-name–i.e. a 3 in this field indicates that the modification is to be applied to the third such header matching the supplied “name” field. A zero length string for “value”, leaving only a single NUL byte, indicates that the header should be deleted entirely.)

fn len(&self) -> usize

Byte-length that would be written if Self::write is called

fn code(&self) -> u8

The (unique) id code of this item

fn is_empty(&self) -> bool

Whether a call to Self::write would write something
