Struct Emission 

pub struct Emission { /* private fields */ }

What one call to a stage produced: the bytes it emitted, how they are framed, and what it asked the host to do about its own schedule.

One struct rather than four borrows because they are written together and read together, and because a stage’s whole answer is exactly these four things. The host keeps one per buffer and resets it between calls, so a steady stream allocates nothing here after the first few chunks.

Implementations

impl Emission

pub fn new() -> Self

pub fn reset(&mut self)

Ready for a fresh call, keeping the allocations.

pub fn bytes(&self) -> &[u8]

Everything the stage emitted, concatenated.

pub fn bounds(&self) -> &[usize]

The framing of bytes. Empty means one unit.

pub fn emit(&self) -> Emit

What the stage did with what it was given.

pub fn rearm_requested(&self) -> bool

Whether the stage asked for its schedule to be restarted. See Ctx::rearm.

Trait Implementations

impl Debug for Emission

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

Formats the value using the given formatter.

impl Default for Emission

fn default() -> Emission

Returns the “default value” for a type.
