Struct varu32

pub struct varu32(pub u32);

A variable length integer type that can be up to 32 bits. This is a helper type for deriving the BinaryIo trait.

You should not use this type directly, if you are reading or writing a variable length integer, use the ByteWriter or ByteReader and use the corresponding read_var_u32 or write_var_u32 methods.

Performs copy-assignment from source.

impl Debug for varu32

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

Formats the value using the given formatter.

impl Deref for varu32

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for varu32

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl From<u32> for varu32

fn from(val: u32) -> Self

Converts to this type from the input type.

impl From<varu32> for u32

fn from(val: varu32) -> Self

Converts to this type from the input type.

impl Hash for varu32

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 Ord for varu32

fn cmp(&self, other: &varu32) -> 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 varu32

fn eq(&self, other: &varu32) -> 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 varu32

fn partial_cmp(&self, other: &varu32) -> 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 Reader<varu32> for varu32

fn read(buf: &mut ByteReader) -> Result<varu32, Error>

Reads Self from a ByteReader.

fn read_from_slice(buf: &[u8]) -> Result<Output, Error>

Reads Self from a &[u8].

impl Writer for varu32

fn write(&self, buf: &mut ByteWriter) -> Result<(), Error>

Writes Self to a ByteWriter.

fn write_to_bytes(&self) -> Result<ByteWriter, Error>

This is a utility function to write Self to a ByteWriter without needing to create a ByteWriter first.
