Enum Request 

pub enum Request<F: Family> {
    Operations {
        size: Location<F>,
        start: Location<F>,
        max_ops: NonZeroU64,
    },
    Boundary {
        size: Location<F>,
        start: Location<F>,
    },
}

A request for operations from a source’s log.

Variants

Operations

Fetch the operations in [start, start + max_ops).

Fields

size: Location<F>

Prove against the root the database had at this size.

start: Location<F>

First operation to return.

max_ops: NonZeroU64

Maximum number of operations to return.

Boundary

Fetch the single operation at start plus the pinned nodes at start, the lowest location the client will retain. The proof in the response authenticates the pinned nodes, so there is no way to request them on their own.

Fields

size: Location<F>

Prove against the root the database had at this size.

start: Location<F>

The operation to return, which is also the location of the returned pinned nodes.

Implementations

impl<F: Family> Request<F>

pub const fn size(&self) -> Location<F>

The size whose root the response’s proof must verify against.

pub const fn start(&self) -> Location<F>

First operation to return.

pub const fn max_ops(&self) -> NonZeroU64

Maximum number of operations to return.

Trait Implementations

impl<F: Family> Clone for Request<F>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Family> Copy for Request<F>

impl<F: Family> Debug for Request<F>

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

Formats the value using the given formatter.

impl<F: Family> Display for Request<F>

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

Formats the value using the given formatter.

impl<F: Family> EncodeSize for Request<F>

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

fn encode_inline_size(&self) -> usize

Returns the encoded size excluding bytes passed to BufsMut::push during Write::write_bufs. Used to size the working buffer for inline writes. Override alongside Write::write_bufs for types where large Bytes fields go via push; failing to do so will over-allocate.

impl<F: Family> Eq for Request<F>

impl<F: Family> Hash for Request<F>

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<F: Family> Ord for Request<F>

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl<F: Family> PartialEq for Request<F>

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl<F: Family> PartialOrd for Request<F>

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<F: Family> Read for Request<F>

type Cfg = ()

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, _: &()) -> Result<Self, CodecError>

Reads a value from the buffer using the provided configuration cfg.

impl<F: Family> Span for Request<F>

impl<F: Family> Write for Request<F>

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

fn write_bufs(&self, buf: &mut impl BufsMut)

Writes to a BufsMut, allowing existing Bytes chunks to be appended via BufsMut::push instead of written inline. Must encode to the same format as Write::write. Defaults to Write::write.
