}

A renderable value stored in a View.

View parts are created through a PartsWriter or the view! macro. A part that holds text also records the HtmlContext it was written for, so rendering escapes or validates it for exactly that position.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

Renders no content.

#[non_exhaustive]

Bool(bool)

A boolean rendered as text.

#[non_exhaustive]

I8(i8)

An i8 rendered as text.

#[non_exhaustive]

I16(i16)

An i16 rendered as text.

#[non_exhaustive]

I32(i32)

An i32 rendered as text.

#[non_exhaustive]

I64(i64)

An i64 rendered as text.

#[non_exhaustive]

I128(i128)

An i128 rendered as text.

#[non_exhaustive]

Isize(isize)

An isize rendered as text.

#[non_exhaustive]

U8(u8)

A u8 rendered as text.

#[non_exhaustive]

An f32 rendered as text.

#[non_exhaustive]

F64(f64)

An f64 rendered as text.

#[non_exhaustive]

Char

A character rendered for the recorded context.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

value: char

context: HtmlContext

#[non_exhaustive]

Str

A string rendered for the recorded context.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

value: Cow<'static, str>

context: HtmlContext

#[non_exhaustive]

BoxDyn

A custom view part that writes its output at render time.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

inner: Box<dyn DynViewPart>

context: HtmlContext

size_hint: usize

#[non_exhaustive]

BoxSlice

A sequence of view parts rendered in order.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

inner: Box<[ViewPart]>

size_hint: usize
