Enum AccessSpec

pub enum AccessSpec {
    ReadOnly,
    ReadWrite,
    ReadWriteOnce,
    WriteOnce,
    WriteOnly,
}

Defines access rights for fields on the device, though it may be specified at a higher level than individual fields.

Values

• ReadOnly = Read access is permitted. Write operations have an undefined effect.
• ReadWrite = Read and write accesses are permitted.
• ReadWriteOnce = Read access is always permitted. Only the first write after a reset will affect the content. Following writes have an undefined effect.
• WriteOnce = Read operations have undefined results. Only the first write after a reset will affect the content.
• WriteOnly = Read operations have an undefined result. Write access is permitted.

Variants

Implementations

impl AccessSpec

pub fn can_read(&self) -> bool

Whether the field is readable at least once.

pub fn can_write(&self) -> bool

Whether the field is writable at least once.

Trait Implementations

impl Clone for AccessSpec

fn clone(&self) -> AccessSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccessSpec

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

Formats the value using the given formatter.

impl PartialEq for AccessSpec

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