Enum Value

pub enum Value {
    Text(String),
    Int(i64),
    Bool(bool),
    Float(f64),
    ArrayOrTuple(Vec<Value>),
    Struct(BTreeMap<String, Value>),
}

Expand description

A cookie cutter value used by the template engine to process data. Also used to provide data to templates in the form of paramters on the initial call to a render* function of a crate::Templates.

Can be obtained several ways:

Constructed programmatically
using the crate::value! value
serializing a Rust value (if the serde feature is enabled)

Variants§

Text(String)

Some text (without text type since that information is erased by render time).

Int(i64)

An integer.

Bool(bool)

A bool.

Float(f64)

A float.

ArrayOrTuple(Vec<Value>)

An array or a tuple (the information whether this value originated from or is destined for an array or a tuple has been erased by render time)

Struct(BTreeMap<String, Value>)

A struct made up of key value pairs

Implementations§

impl Value

pub fn is_printable(&self) -> bool

Determines whether the given value can be turned into a string a.k.a is “printable”.

fn fg(&self, value: Color) -> Painted<&T>

Returns a styled value derived from self with the foreground set to value.

This method should be used rarely. Instead, prefer to use color-specific builder methods like red() and green(), which have the same functionality but are pithier.

painted.fg(Color::White);

Set foreground color to white using white().
