Enum Access 

#[non_exhaustive]
#[repr(u32)]
pub enum Access {
    MmapInterleaved = 0,
    MmapNoninterleaved = 1,
    MmapComplex = 2,
    ReadWriteInterleaved = 3,
    ReadWriteNoninterleaved = 4,
}

Available on crate feature alsa only.

Defines how the underlying device is accessed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MmapInterleaved = 0

MMAP access with simple interleaved channels

MmapNoninterleaved = 1

MMAP access with simple non interleaved channels

MmapComplex = 2

MMAP access with complex placement

ReadWriteInterleaved = 3

Interleaved read/write access

ReadWriteNoninterleaved = 4

Sequential read/write access

Implementations

impl Access

pub fn from_value(value: u32) -> Option<Self>

Parse the given enum from a value.

Trait Implementations

impl Clone for Access

fn clone(&self) -> Access

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Access

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

Formats the value using the given formatter.

impl Display for Access

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

Formats the value using the given formatter.

impl Hash for Access

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 Ord for Access

fn cmp(&self, other: &Access) -> 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 Access

fn eq(&self, other: &Access) -> 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 Access

fn partial_cmp(&self, other: &Access) -> 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.

impl Copy for Access

impl Eq for Access
