Struct ConstantData

pub struct ConstantData(/* private fields */);

This type represents the raw data of a constant.

The data is expected to be in little-endian order.

Implementations

impl ConstantData

pub fn len(&self) -> usize

Return the number of bytes in the constant.

pub fn is_empty(&self) -> bool

Check if the constant contains any bytes.

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

Return the data as a slice.

pub fn append(self, bytes: impl IntoBytes) -> Self

Append bytes to this constant

pub fn zext(self, expected_size: usize) -> Self

Grow the size of the constant data in bytes to expected_size, zero-extending the data by writing zeroes to the newly-added high-order bytes.

pub fn as_u32(&self) -> Option<u32>

Attempt to convert this constant data to a u32 value

impl ConstantData

pub fn from_str_be(s: &str) -> Result<Self, &'static str>

pub fn from_str_le(s: &str) -> Result<Self, &'static str>

Trait Implementations

impl Clone for ConstantData

fn clone(&self) -> ConstantData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstantData

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

Formats the value using the given formatter.

impl Default for ConstantData

fn default() -> ConstantData

Returns the “default value” for a type.

impl Display for ConstantData

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

Print the constant data in hexadecimal format, e.g. 0x000102030405060708090a0b0c0d0e0f.

The printed form of the constant renders the bytes in big-endian order, for readability.

impl From<&[u8]> for ConstantData

fn from(v: &[u8]) -> Self

Converts to this type from the input type.

impl<const N: usize> From<[u8; N]> for ConstantData

fn from(v: [u8; N]) -> Self

Converts to this type from the input type.

impl From<ConstantData> for Vec<u8>

fn from(data: ConstantData) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for ConstantData

fn from(v: Vec<u8>) -> Self

Converts to this type from the input type.

impl FromIterator<u8> for ConstantData

fn from_iter<T: IntoIterator<Item = u8>>(iter: T) -> Self

Creates a value from an iterator.

impl FromStr for ConstantData

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ConstantData

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 LowerHex for ConstantData

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

Print the constant data in hexadecimal format, e.g. 0x000102030405060708090a0b0c0d0e0f.

The printed form of the constant renders the bytes in the same order as the data.

impl Ord for ConstantData

fn cmp(&self, other: &ConstantData) -> 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.

impl PartialEq for ConstantData

fn eq(&self, other: &ConstantData) -> 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 PartialOrd for ConstantData

fn partial_cmp(&self, other: &ConstantData) -> 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.
