Struct tor_cell::relaycell::msg::Data

source · [−]

pub struct Data { /* private fields */ }

Expand description

A Data message represents data sent along a stream.

Upon receiving a Data message for a live stream, the client or exit sends that data onto the associated TCP connection.

These messages hold between 1 and Data::MAXLEN bytes of data each; they are the most numerous messages on the Tor network.

Implementations

source

impl Data

source

pub const MAXLEN: usize = 498usize

The longest allowable body length for a single data cell.

source

pub fn new(inp: &[u8 ]) -> Result<Self>

Construct a new data cell.

Returns an error if inp is longer than Data::MAXLEN bytes.

source

pub fn split_from(inp: &[u8 ]) -> (Self, &[u8 ])

Construct a new data cell, taking as many bytes from inp as possible.

Return the data cell, and a slice holding any bytes that wouldn’t fit (if any).

Trait Implementations
