Struct TypeSize 

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

Byte size of a fixed-bytes, integer, or fixed-point number (M) type. Valid values: 0..=32.

Implementations

impl TypeSize

pub const ZERO: Self

The value zero. Note that this is not a valid size for a fixed-bytes type.

pub const MAX: u8 = 32u8

The maximum byte value of a TypeSize.

pub const fn new(bytes: u8) -> Option<Self>

Creates a new TypeSize from a u8 number of bytes.

pub fn new_int_bits(bits: u16) -> Self

Creates a new TypeSize from a u8 number of bits.

Panics if bits is not a multiple of 8 or greater than 256.

pub fn try_new_int_bits(bits: u16) -> Option<Self>

Creates a new TypeSize for an integer type.

Returns None if bits is not a multiple of 8 or greater than 256.

pub fn new_fb_bytes(bytes: u8) -> Self

Creates a new TypeSize for a fixed-bytes type.

Panics if bytes is not in the range 1..=32.

pub fn try_new_fb_bytes(bytes: u8) -> Option<Self>

Creates a new TypeSize for a fixed-bytes type.

Returns None if bytes is not in the range 1..=32.

pub const fn bytes(self) -> u8

Returns the number of bytes, with 0 defaulting to MAX.

pub const fn bytes_raw(self) -> u8

Returns the number of bytes.

pub const fn bits(self) -> u16

Returns the number of bits, with 0 defaulting to MAX*8.

pub const fn bits_raw(self) -> u16

Returns the number of bits.

pub const fn int_keyword(self) -> Symbol

Returns the int symbol for the type name.

pub const fn uint_keyword(self) -> Symbol

Returns the uint symbol for the type name.

pub const fn bytes_keyword(self) -> Symbol

Returns the bytesN symbol for the type name.

Panics

Panics if self is 0.

Trait Implementations

impl Clone for TypeSize

fn clone(&self) -> TypeSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeSize

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

Formats the value using the given formatter.

impl Hash for TypeSize

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 TypeSize

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

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
