Struct BlockContext

pub struct BlockContext<'rc> { /* private fields */ }

A data structure holds contextual data for current block scope.

Implementations

impl<'rc> BlockContext<'rc>

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

create a new BlockContext with default data

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

set a local variable into current scope

pub fn local_variables_mut(&mut self) -> &mut LocalVars

Get mutable access to the local variables

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

get a local variable from current scope

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

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

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

borrow a mutable reference to the base path

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

borrow the base value

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

set the base value

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}}

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

Reassign the block parameters for this block.

pub fn set_block_param(&mut self, key: &'rc str, value: BlockParamHolder)

Set a block parameter into this block.

Trait Implementations

impl<'rc> Clone for BlockContext<'rc>

fn clone(&self) -> BlockContext<'rc>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'rc> Debug for BlockContext<'rc>

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

Formats the value using the given formatter.

impl<'rc> Default for BlockContext<'rc>

fn default() -> BlockContext<'rc>

Returns the “default value” for a type.
