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: TypeSize

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<TypeSize>

Creates a new TypeSize from a u8 number of bytes.

pub fn new_int_bits(bits: u16) -> TypeSize

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<TypeSize>

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) -> TypeSize

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<TypeSize>

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<(), Error>

Formats the value using the given formatter.

impl Hash for TypeSize

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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.
