pub struct State { /* private fields */ }

Monotonic committed prefix of one bounded transfer.

Implementations

impl State

pub const fn new(limit: Len) -> Self

pub const fn is_empty(&self) -> bool

pub const fn left(&self) -> Len

Returns the uncommitted suffix without discarding its backend bound.

pub const fn len(&self) -> Len

pub fn reserve(&mut self, limit: Len) -> Step<'_>

pub fn scatter<'a>( &mut self, cursor: &mut impl Scatter<'a>, ) -> Option<Chunk<'a, { transfer::MAX_BYTES }>>

Advances an exact scatter cursor within this transfer’s remaining budget.

pub fn try_extend(&self, amount: Len) -> Result<Self, Exceeded>

Prepares an exact extended state when the whole amount fits.
