pub struct BlockContext<'reg> { /* private fields */ }
Expand description

A data structure holds contextual data for current block scope.

Implementations§

source§

impl<'reg> BlockContext<'reg>

source

pub fn new() -> BlockContext<'reg>

create a new BlockContext with default data

source

pub fn set_local_var(&mut self, name: &str, value: Value)

set a local variable into current scope

source

pub fn get_local_var(&self, name: &str) -> Option<&Value>

get a local variable from current scope

source

pub fn base_path(&self) -> &Vec<String, Global>

borrow a reference to current scope’s base path all paths inside this block will be relative to this path

source

pub fn base_path_mut(&mut self) -> &mut Vec<String, Global>

borrow a mutable reference to the base path

source

pub fn base_value(&self) -> Option<&Value>

borrow the base value

source

pub fn set_base_value(&mut self, value: Value)

set the base value

source

pub fn get_block_param( &self, block_param_name: &str ) -> Option<&BlockParamHolder>

Get a block parameter from this block. Block parameters needed to be supported by the block helper. The typical syntax for block parameter is:

{{#myblock param1 as |block_param1|}}
   ...
{{/myblock}}
source

pub fn set_block_params(&mut self, block_params: BlockParams<'reg>)

Set a block parameter into this block.
