Trait Implementations

impl PartialOrd<ReadMode> for ReadMode

fn partial_cmp(&self, other: &ReadMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for ReadMode

fn cmp(&self, other: &ReadMode) -> Ordering

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl PartialEq<ReadMode> for ReadMode

fn eq(&self, other: &ReadMode) -> bool

This method tests for self and other values to be equal, and is used by ==.
