Trait askama::DynTemplate

pub trait DynTemplate {
    // Required methods
    fn dyn_render(&self) -> Result<String>;
    fn dyn_render_into(&self, writer: &mut dyn Write) -> Result<()>;
    fn dyn_write_into(&self, writer: &mut dyn Write) -> Result<()>;
    fn extension(&self) -> Option<&'static str>;
    fn size_hint(&self) -> usize;
    fn mime_type(&self) -> &'static str;
}

Object-safe wrapper trait around Template implementers

This trades reduced performance (mostly due to writing into dyn Write) for object safety.

Required Methods

fn dyn_render(&self) -> Result<String>

Helper method which allocates a new String and renders into it

fn dyn_render_into(&self, writer: &mut dyn Write) -> Result<()>

Renders the template to the given writer fmt buffer

fn dyn_write_into(&self, writer: &mut dyn Write) -> Result<()>

Renders the template to the given writer io buffer

fn extension(&self) -> Option<&'static str>

Helper function to inspect the template’s extension

fn size_hint(&self) -> usize

Provides a conservative estimate of the expanded length of the rendered template

fn mime_type(&self) -> &'static str

The MIME type (Content-Type) of the data that gets rendered by this Template
