[−][src]Struct markings::Template
Template allows for string replacement by name
let world = "world"; let message = Template::parse("hello, ${world}!") .unwrap() .apply(&Args::new().with("world", &world).build()) .unwrap(); println!("{}", message); // => hello, world!
Methods
impl Template
[src]
pub fn find_keys(
input: &str,
x: fn(_: &char) -> bool,
xs: fn(_: &char) -> bool
) -> Result<Vec<&str>, KeyError>
[src]
input: &str,
x: fn(_: &char) -> bool,
xs: fn(_: &char) -> bool
) -> Result<Vec<&str>, KeyError>
Find all of the keys in the template, returning their names
This will return an error on:
- Duplicate keys
- Unsupported templates (e.g. nested)
- Empty Templates (so you can skip parsing/application)
- Failure of the
x
cmp function - Failure of the
xs
cmp function
See KeyError
for errors this can return
x
is a comparison function that is applied to the first character of each key
xs
is a comparison function that is applied to the rest of the key
pub fn parse(input: &str) -> Result<Self, Error>
[src]
Parses a new template from a string
The syntax is extremely basic: just ${key}
It gets replaced by a value matching the key during the Template::apply
call
pub fn apply<'repr, I, V>(self, parts: I) -> Result<String, Error> where
I: IntoIterator<Item = &'repr (&'repr str, V)> + 'repr,
V: Display + 'repr,
[src]
I: IntoIterator<Item = &'repr (&'repr str, V)> + 'repr,
V: Display + 'repr,
Apply the arguments to the template
One can use the Args
builder to make this less tedious
