Struct jens::Block

pub struct Block(pub Vec<Line>);

A Block is one or many lines of text. More blocks can be embedded within a line, in which case the indentation of the previous line will be preserved when outputting new lines.

Methods

impl Block

pub fn empty() -> Self

pub fn write_to(&self, f: &mut Formatter, prefix: &str) -> Result

pub fn set<T: Into<Block>>(self, placeholder_name: &str, content: T) -> Self

pub fn join_map<T, U, F>(iter: T, mapper: F) -> Self where
    T: IntoIterator<Item = U>,
    F: Fn(U, IteratorLocation) -> Block, 

Run a function that maps over each item in an iterator, then join the results.

Provides an IteratorLocation for checking whether the current item is the first/last/only/nth item in the list.

pub fn for_each<T, U, F>(self, iter: T, mapper: F) -> Self where
    T: IntoIterator<Item = U>,
    F: Fn(U, Block) -> Block, 

Deprecated

Repeat a template for each element of some iterable value.

Deprecated in favor of join_map.

pub fn join<T>(blocks: T) -> Block where
    T: IntoIterator<Item = Block>, 

Join multiple blocks into a single block
