#[repr(transparent)]
pub struct Tag(pub u32);

[−] Expand description

A 4-byte tag.

Implementations

impl Tag[−]

pub const fn from_bytes(bytes: &[u8; 4]) -> Tag[−]

Creates a Tag from bytes.

pub fn from_bytes_lossy(bytes: &[u8]) -> Tag[−]

Creates a Tag from bytes.

In case of empty data will return Tag set to 0.

When bytes are shorter than 4, will set missing bytes to .

Data after first 4 bytes is ignored.

pub const fn to_bytes(self) -> [u8; 4][−]

Returns tag as 4-element byte array.

pub const fn to_chars(self) -> [char; 4][−]

Returns tag as 4-element byte array.

pub const fn is_null(&self) -> bool[−]

Checks if tag is null / [0, 0, 0, 0].

pub const fn as_u32(&self) -> u32[−]

Returns tag value as u32 number.

pub fn to_lowercase(&self) -> Tag[−]

Converts tag to lowercase.

pub fn to_uppercase(&self) -> Tag[−]

Converts tag to uppercase.
