Enum FormatParamUsage

pub enum FormatParamUsage {
    Argument,
    Width,
    Precision,
}

Where a format parameter is being used in the format string

Variants

Argument

Appears as an argument, e.g. format!("{}", foo)

Width

Trait Implementations

impl Clone for FormatParamUsage

fn clone(&self) -> FormatParamUsage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FormatParamUsage

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

Formats the value using the given formatter.

impl PartialEq for FormatParamUsage

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