Enum rustls::crypto::cipher::OutboundChunks

source ·
pub enum OutboundChunks<'a> {
    Single(&'a [u8]),
    Multiple {
        chunks: &'a [&'a [u8]],
        start: usize,
        end: usize,
    },
}
Expand description

A collection of borrowed plaintext slices.

Warning: OutboundChunks does not guarantee that the simplest variant is used. Multiple can hold non fragmented or empty payloads.

Variants§

§

Single(&'a [u8])

A single byte slice. Contrary to Multiple, this uses a single pointer indirection

§

Multiple

A collection of chunks (byte slices) and cursors to single out a fragmented range of bytes. OutboundChunks assumes that start <= end

Fields

§chunks: &'a [&'a [u8]]
§start: usize
§end: usize

Implementations§

source§

impl<'a> OutboundChunks<'a>

source

pub fn new(chunks: &'a [&'a [u8]]) -> Self

Create a payload from a slice of byte slices. If fragmented the cursors are added by default: start = 0, end = length

source

pub fn new_empty() -> Self

Create a payload with a single empty slice

source

pub fn to_vec(&self) -> Vec<u8>

Flatten the slice of byte slices to an owned vector of bytes

source

pub fn copy_to_vec(&self, vec: &mut Vec<u8>)

Append all bytes to a vector

source

pub fn split_at(&self, mid: usize) -> (Self, Self)

Split self in two, around an index Works similarly to split_at in the core library, except it doesn’t panic if out of bound

source

pub fn is_empty(&self) -> bool

Returns true if the payload is empty

source

pub fn len(&self) -> usize

Returns the cumulative length of all chunks
