Struct alkahest::FixedIsize

#[repr(transparent)]
pub struct FixedIsize(_);

Type used to represent sizes and offsets in serialized data. This places limitation on sequence sizes which practically is never hit. usize itself is not portable and cannot be written into alkahest package.

Implementations

impl FixedIsize

pub fn truncate_unchecked(value: isize) -> Self

Truncates isize to FixedIsizeType without checking.

pub fn to_le_bytes(self) -> [u8; 4]

Converts to byte array in little endian.

pub fn from_le_bytes(bytes: [u8; 4]) -> Result<Self, TryFromIntError>

Converts from byte array in little endian.

Errors

Returns Err if the byte array does not represent a valid isize.

impl Ord for FixedIsize

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

This method returns an Ordering between self and other.

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

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

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

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

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

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

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

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

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

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

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

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