Enum Value

pub enum Value<'a> {
    Num(u64),
    Bytes(&'a [u8]),
}

A values that stores its byte data as a &[u8].

Variants

Num(u64)

An integer value.

Bytes(&'a [u8])

Byte data

Implementations

impl Value<'_>

pub fn to_le_bytes(&self) -> Vec<u8>

Converts the value to little-endian bytes.

pub fn select_byte(&self, index: usize) -> u8

Returns the byte at position index in the value. For integers, returns (val >> (index * 8)) as u8

pub fn slice(&self, size: Size) -> Self

Slices the value to include only the area in size.

pub fn xor<T>(&self, b: &Value<'_>, f: impl FnMut(&Value<'_>) -> T) -> T

Computes the XOR of this value and b. The result is provided to f.

pub fn or<T>(&self, b: &Value<'_>, f: impl FnMut(&Value<'_>) -> T) -> T

Computes the OR of this value and b. The result is provided to f.

pub fn and<T>(&self, b: &Value<'_>, f: impl FnMut(&Value<'_>) -> T) -> T

Computes the AND of this value and b. The result is provided to f.

Trait Implementations

impl AsValue for Value<'_>

fn as_value(&self) -> Value<'_>

Returns a reference to the value as a Value.

fn unwrap_num(&self) -> u64

If the value is an integer, returns the integer. Otherwise, panics.

fn unwrap_bytes(&self) -> &[u8]

If the value is Byte data, returns a reference to the bytestring. Otherwise, panics.

fn interpret_as_bool(&self) -> bool

If the value is an integer, returns true if and only if the integer is non-zero. Otherwise, panics.

fn to_owned_value(&self) -> OwnedValue

Converts the value to an OwnedValue.

impl<'a> Clone for Value<'a>

fn clone(&self) -> Value<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value<'_>

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

Formats the value using the given formatter.

impl Equivalent<OwnedValue> for Value<'_>

fn equivalent(&self, key: &OwnedValue) -> bool

Checks if this value is equivalent to the given key.

impl Equivalent<Value<'_>> for OwnedValue

fn equivalent(&self, key: &Value<'_>) -> bool

Checks if this value is equivalent to the given key.

impl<'a> From<Value<'a>> for OwnedValue

fn from(value: Value<'a>) -> Self

Converts to this type from the input type.

impl<'a> Hash for Value<'a>

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 PartialEq<OwnedValue> for Value<'_>

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialEq<Value<'a>> for OwnedValue

fn eq(&self, other: &Value<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PartialEq for Value<'a>

fn eq(&self, other: &Value<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl UpperHex for Value<'_>

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

Formats the value using the given formatter.

impl<'a> Copy for Value<'a>

impl<'a> Eq for Value<'a>

impl<'a> StructuralPartialEq for Value<'a>
