Enum Item

pub enum Item<'a> {
    Literal(&'a str),
    OwnedLiteral(Box<str>),
    Space(&'a str),
    OwnedSpace(Box<str>),
    Numeric(Numeric, Pad),
    Fixed(Fixed),
    Error,
}

A single formatting item. This is used for both formatting and parsing.

Variants

Literal(&'a str)

A literally printed and parsed text.

OwnedLiteral(Box<str>)

Same as Literal but with the string owned by the item.

Space(&'a str)

Whitespace. Prints literally but reads zero or more whitespace.

OwnedSpace(Box<str>)

Same as Space but with the string owned by the item.

Numeric(Numeric, Pad)

Numeric item. Can be optionally padded to the maximal length (if any) when formatting; the parser simply ignores any padded whitespace and zeroes.

Fixed(Fixed)

Fixed-format item.

Error

Issues a formatting error. Used to signal an invalid format string.

Implementations

impl<'a> Item<'a>

pub fn to_owned(self) -> Item<'static>

Convert items that contain a reference to the format string into an owned variant.

Trait Implementations

impl<'a> Clone for Item<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Item<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Item<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for Item<'a>

fn eq(&self, other: &Item<'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.
