Struct IfmtInput

pub struct IfmtInput {
    pub source: LitStr,
    pub segments: Vec<Segment>,
}

A hot-reloadable formatted string, boolean, number or other literal

This wraps LitStr with some extra goodies like inline expressions and hot-reloading. Originally this was intended to provide named inline string interpolation but eventually Rust actually shipped this!

Fields

source: LitStr

segments: Vec<Segment>

Implementations

impl IfmtInput

pub fn new(span: Span) -> Self

pub fn new_litstr(source: LitStr) -> Result<Self>

pub fn span(&self) -> Span

pub fn push_raw_str(&mut self, other: String)

pub fn push_ifmt(&mut self, other: IfmtInput)

pub fn push_expr(&mut self, expr: Expr)

pub fn is_static(&self) -> bool

pub fn to_static(&self) -> Option<String>

pub fn dynamic_segments(&self) -> Vec<&FormattedSegment>

pub fn dynamic_seg_frequency_map(&self) -> HashMap<&FormattedSegment, usize>

pub fn to_string_with_quotes(&self) -> String

print the original source string - this handles escapes and stuff for us

Trait Implementations

impl Clone for IfmtInput

fn clone(&self) -> IfmtInput

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IfmtInput

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

Formats the value using the given formatter.

impl From<IfmtInput> for HotReloadFormattedSegment

fn from(input: IfmtInput) -> Self

Converts to this type from the input type.

impl Hash for IfmtInput

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 Parse for IfmtInput

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for IfmtInput

fn eq(&self, other: &IfmtInput) -> 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 ToTokens for IfmtInput

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
