Implementations

impl Mode

pub fn readable(&self) -> bool

match self {
    Self::Read | Self::ReadReplace | Self::ReadAppend => true,
    _ => false,
}

pub fn writable(&self) -> bool

match self {
    Self::Replace | Self::Append | Self::ReadAppend | Self::ReadReplace => true,
    _ => false,
}

pub fn appendable(&self) -> bool

match self {

    _ => false,
}

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl Default for Mode

fn default() -> Mode

Returns the “default value” for a type.

impl PartialEq for Mode

fn eq(&self, other: &Mode) -> 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 Copy for Mode

impl StructuralPartialEq for Mode
