👎Deprecated: This project is no longer maintained, use the hound crate

Structure for the "fmt " chunk of wave files, specifying key information about the enclosed data.

This struct supports only PCM and IEEE float data, which is to say there is no extra members for compressed format data.

Implementations

impl Header

pub fn new( audio_format: u16, channel_count: u16, sampling_rate: u32, bits_per_sample: u16, ) -> Header

👎Deprecated: This project is no longer maintained, use the hound crate

Creates a new Header object.

Note

While the crate::read and crate::write functions only support uncompressed PCM/IEEE for the audio format, the option is given here to select any audio format for custom implementations of wave features.

Parameters

• audio_format - Audio format. Only WAV_FORMAT_PCM (0x01) and WAV_FORMAT_IEEE_FLOAT (0x03) are supported.
• channel_count - Channel count. The number of channels each sample has. Generally 1 (mono) or 2 (stereo).
• sampling_rate - Sampling rate (e.g. 44.1kHz, 48kHz, 96kHz, etc.).
• bits_per_sample - Number of bits in each (sub-channel) sample. Generally 8, 16, 24, or 32.

Example

let h = wav::Header::new(wav::header::WAV_FORMAT_PCM, 2, 48_000, 16);

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl From<[u8; 16]> for Header

fn from(v: [u8; 16]) -> Self

Converts to this type from the input type.

impl From<Header> for [u8; 16]

fn from(h: Header) -> Self

Converts to this type from the input type.

impl Hash for Header

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 Header

fn eq(&self, other: &Header) -> 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 TryFrom<&[u8]> for Header

fn try_from(v: &[u8]) -> Result<Self, Self::Error>

Errors

This function will return an error if the given slice is smaller than 16 bytes.

type Error = &'static str

The type returned in the event of a conversion error.

impl Copy for Header

impl Eq for Header

impl StructuralPartialEq for Header
