Struct StringTemplate 

pub struct StringTemplate { /* private fields */ }

A parsed string template, containing a series of [Part]s.

Implementations

impl StringTemplate

pub fn parse_with_spec(input: &str, spec: ConnectSpec) -> Result<Self, Error>

impl StringTemplate

pub fn interpolate( &self, vars: &IndexMap<String, Value>, ) -> Result<(String, Vec<ApplyToError>), Error>

Interpolate the expressions in the template into a basic string.

For URIs, use Self::interpolate_uri instead.

pub fn interpolate_uri( &self, vars: &IndexMap<String, Value>, ) -> Result<(Uri, Vec<ApplyToError>), Error>

Interpolate the expression as a URI, percent-encoding parts as needed.

Trait Implementations

impl Clone for StringTemplate

fn clone(&self) -> StringTemplate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringTemplate

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

Formats the value using the given formatter.

impl Default for StringTemplate

fn default() -> StringTemplate

Returns the “default value” for a type.

impl Display for StringTemplate

Expressions should be written the same as they were originally, even though we don’t keep the original source around. So constants are written as-is and expressions are surrounded with { }.

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

Formats the value using the given formatter.

impl FromStr for StringTemplate

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a StringTemplate from a &str, using ConnectSpec::V0_2 as the parsing version. This trait implementation should be avoided outside tests because it runs the risk of ignoring the developer’s chosen ConnectSpec if used blindly via .parse(), since FromStr gives no opportunity to specify additional context like the ConnectSpec.

type Err = Error

The associated error which can be returned from parsing.
