Struct TemplateBuffer 

pub struct TemplateBuffer<'a> { /* private fields */ }

A template buffer. This is the type that gets passed to closures inside templates.

Example:

    html! {
        |tmpl /*: &mut TemplateBuffer */| tmpl << "Some String";
    };

Implementations

impl<'a> TemplateBuffer<'a>

pub fn record_error<E: Into<Box<dyn Error + Send + Sync>>>(&mut self, e: E)

Record an error. If a template calls this function, rendering will be short-circuited and the error will be returned to the user.

FEATURE:

• With “alloc” but without “std”, accepts anything that can be converted to a string (anything implementing ToString).
• Without “std” or “alloc”, accepts a static &str. Multiple calls will record the first error.

pub fn write_raw(&mut self, text: &str)

Write a raw string to the template output.

pub fn write_fmt(&mut self, args: Arguments<'_>)

Escape and write the formatted arguments to the template output.

Example:

write!(tmpl, "{} + {}", 0, 1);

pub fn write_str(&mut self, text: &str)

Escape and write a string to the template output.

pub fn as_writer<'b>(&'b mut self) -> TemplateWriter<'a, 'b>

Returns an escaping Write adapter.

pub fn as_raw_writer<'b>(&'b mut self) -> RawTemplateWriter<'a, 'b>

Returns a non-escaping Write adapter.

Trait Implementations

impl<'a, 'b, T> Shl<T> for &'a mut TemplateBuffer<'b>

where T: RenderOnce,

fn shl(self, component: T)

Render the component into the template.

Note: If writing to the template fails, this method will neither panic nor return errors. Instead, no more data will be written to the template and horrorshow abort template rendering (return an error) when it re-gains control.

type Output = ()

The resulting type after applying the << operator.
