}Expand description
Trait allowing the rendering to quickly access data stored in the type that
implements it. You needn’t worry about implementing it, in virtually all
cases the #[derive(Content)] attribute above your types should be sufficient.
Provided Methods
Marks whether this content is truthy. Used when attempting to render a section.
fn capacity_hint(&self, _tpl: &Template<'_>) -> usize
fn capacity_hint(&self, _tpl: &Template<'_>) -> usize
How much capacity is likely required for all the data in this Content
for a given Template.
Renders self as a variable to the encoder.
This will escape HTML characters, eg: < will become <.
Renders self as a variable to the encoder.
This doesn’t perform any escaping at all.
fn render_section<C, E>(
&self,
section: Section<'_, C>,
encoder: &mut E
) -> Result<(), E::Error> where
C: ContentSequence,
E: Encoder,
fn render_section<C, E>(
&self,
section: Section<'_, C>,
encoder: &mut E
) -> Result<(), E::Error> where
C: ContentSequence,
E: Encoder,
Render a section with self.
fn render_inverse<C, E>(
&self,
section: Section<'_, C>,
encoder: &mut E
) -> Result<(), E::Error> where
C: ContentSequence,
E: Encoder,
fn render_inverse<C, E>(
&self,
section: Section<'_, C>,
encoder: &mut E
) -> Result<(), E::Error> where
C: ContentSequence,
E: Encoder,
Render a section with self.
Render a field by the hash or string of its name.
This will escape HTML characters, eg: < will become <.
If successful, returns true if the field exists in this content, otherwise false.
Render a field by the hash or string of its name.
This doesn’t perform any escaping at all.
If successful, returns true if the field exists in this content, otherwise false.
Render a field by the hash or string of its name, as a section.
If successful, returns true if the field exists in this content, otherwise false.
Render a field, by the hash of or string its name, as an inverse section.
If successful, returns true if the field exists in this content, otherwise false.
