Enum ics23::LengthOp

#[repr(i32)]
pub enum LengthOp {
    NoPrefix,
    VarProto,
    VarRlp,
    Fixed32Big,
    Fixed32Little,
    Fixed64Big,
    Fixed64Little,
    Require32Bytes,
    Require64Bytes,
}

LengthOp defines how to process the key and value of the LeafOp to include length information. After encoding the length with the given algorithm, the length will be prepended to the key and value bytes. (Each one with it's own encoded length)

Variants

NoPrefix

NO_PREFIX don't include any length info

VarProto

VAR_PROTO uses protobuf (and go-amino) varint encoding of the length

VarRlp

VAR_RLP uses rlp int encoding of the length

Fixed32Big

FIXED32_BIG uses big-endian encoding of the length as a 32 bit integer

Fixed32Little

FIXED32_LITTLE uses little-endian encoding of the length as a 32 bit integer

Fixed64Big

FIXED64_BIG uses big-endian encoding of the length as a 64 bit integer

Fixed64Little

FIXED64_LITTLE uses little-endian encoding of the length as a 64 bit integer

Require32Bytes

REQUIRE_32_BYTES is like NONE, but will fail if the input is not exactly 32 bytes (sha256 output)

Require64Bytes

REQUIRE_64_BYTES is like NONE, but will fail if the input is not exactly 64 bytes (sha512 output)

Methods

impl LengthOp

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of LengthOp.

pub fn from_i32(value: i32) -> Option<LengthOp>

Converts an i32 to a LengthOp, or None if value is not a valid variant.

Trait Implementations

impl From<LengthOp> for i32

fn from(value: LengthOp) -> i32

Performs the conversion.

impl Ord for LengthOp

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

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

Restrict a value to a certain interval.

impl PartialOrd<LengthOp> for LengthOp

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

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

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

impl PartialEq<LengthOp> for LengthOp

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Default for LengthOp

fn default() -> LengthOp

Returns the "default value" for a type.

impl Clone for LengthOp

fn clone(&self) -> LengthOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for LengthOp

impl Copy for LengthOp

impl Debug for LengthOp

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