Struct FourCharCode 

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

FourCharCode represents a 4-character code (used in Core Video/Media)

Examples

use screencapturekit::FourCharCode;

// Create from string
let code: FourCharCode = "BGRA".parse().unwrap();
assert_eq!(code.display(), "BGRA");

// Create from bytes
let code = FourCharCode::from_bytes(*b"420v");
assert_eq!(code.as_u32(), 0x34323076);

Implementations

impl FourCharCode

pub const fn from_bytes(bytes: [u8; 4]) -> Self

Create a FourCharCode from exactly 4 bytes (infallible)

Examples

use screencapturekit::FourCharCode;

let code = FourCharCode::from_bytes(*b"BGRA");
assert_eq!(code.display(), "BGRA");

pub fn from_slice(bytes: &[u8]) -> Option<Self>

Create a FourCharCode from a byte slice

pub const fn as_u32(self) -> u32

Get the u32 representation

Examples

use screencapturekit::FourCharCode;

let code = FourCharCode::from_bytes(*b"BGRA");
let value: u32 = code.as_u32();
assert_eq!(value, 0x42475241);

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

Get the bytes as an array

pub const fn from_u32(value: u32) -> Self

Create from a u32 value (const version of From trait)

pub const fn equals(self, other: Self) -> bool

Compare with another FourCharCode at compile time

pub fn display(self) -> String

Display the code as a string

Trait Implementations

impl Clone for FourCharCode

fn clone(&self) -> FourCharCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FourCharCode

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

Formats the value using the given formatter.

impl Display for FourCharCode

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

Formats the value using the given formatter.

impl From<FourCharCode> for PixelFormat

fn from(val: FourCharCode) -> Self

Converts to this type from the input type.

impl From<FourCharCode> for u32

fn from(code: FourCharCode) -> Self

Converts to this type from the input type.

impl From<PixelFormat> for FourCharCode

fn from(val: PixelFormat) -> Self

Converts to this type from the input type.

impl From<u32> for FourCharCode

fn from(value: u32) -> Self

Converts to this type from the input type.

impl FromStr for FourCharCode

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for FourCharCode

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 PartialEq for FourCharCode

fn eq(&self, other: &FourCharCode) -> 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.
