Methods
impl Format
[src]
impl Format
pub fn size(&self) -> usize
[src]
pub fn size(&self) -> usize
Similar to Spec::sample_size
but take a sample
format instead of full sample spec.
pub fn to_string(&self) -> Option<Cow<'static, str>>
[src]
pub fn to_string(&self) -> Option<Cow<'static, str>>
Returns a descriptive string for the specified sample format.
pub fn parse(format: &str) -> Self
[src]
pub fn parse(format: &str) -> Self
Parse a sample format text. Inverse of to_string
.
pub fn is_le(&self) -> Option<bool>
[src]
pub fn is_le(&self) -> Option<bool>
Returns true
when the specified format is little endian, false
if big endian. Returns
None
when endianness does not apply to this format, or if unknown.
pub fn is_be(&self) -> Option<bool>
[src]
pub fn is_be(&self) -> Option<bool>
Returns true
when the specified format is big endian, false
if little endian. Returns
None
when endianness does not apply to this format, or if unknown.
pub fn is_ne(&self) -> Option<bool>
[src]
pub fn is_ne(&self) -> Option<bool>
Is format native endian?
Returns true
when the specified format is native endian, false
when not. Returns None
when endianness does not apply to the specified format, or endianness is unknown
pub fn is_re(&self) -> Option<bool>
[src]
pub fn is_re(&self) -> Option<bool>
Is format reverse of native endian?
Returns true
when the specified format is reverse endian, false
when not. Returns None
when endianness does not apply to the specified format, or endianness is unknown.
