Struct Format

pub(crate) struct Format<'a> {
    span: &'a str,
    parameter: Option<u16>,
    flags: &'a str,
    width: Option<Num>,
    precision: Option<Num>,
    length: Option<&'a str>,
    type_: &'a str,
    position: InnerSpan,
}

A single printf-style formatting directive.

Fields

span: &'a str

The entire original formatting directive.

parameter: Option<u16>

The (1-based) parameter to be converted.

flags: &'a str

Formatting flags.

width: Option<Num>

Minimum width of the output.

precision: Option<Num>

Precision of the conversion.

length: Option<&'a str>

Length modifier for the conversion.

type_: &'a str

Type of parameter being converted.

position: InnerSpan

Byte offset for the start and end of this formatting directive.

Implementations

impl Format<'_>

pub(crate) fn translate(&self) -> Result<String, Option<String>>

Translate this directive into an equivalent Rust formatting directive.

Returns Err in cases where the printf directive does not have an exact Rust equivalent, rather than guessing.

Trait Implementations

impl<'a> Clone for Format<'a>

fn clone(&self) -> Format<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Format<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Format<'a>

fn eq(&self, other: &Format<'a>) -> 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<'a> StructuralPartialEq for Format<'a>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
