Enum Content 

pub enum Content {
    Text(TextContent),
    Image(ImageContent),
    Audio(AudioContent),
    ResourceLink(ResourceLinkContent),
    EmbeddedResource(EmbeddedResource),
    Unknown(UnknownContent),
}

A content block.

Variants

Text(TextContent)

A text block. Every revision, every transport.

Image(ImageContent)

A base64-encoded image. Every revision.

Audio(AudioContent)

Base64-encoded audio. 2025-03-26.

ResourceLink(ResourceLinkContent)

A link to a resource the client can read. 2025-06-18.

EmbeddedResource(EmbeddedResource)

The resource’s contents inline. Every revision.

Unknown(UnknownContent)

A content block this build does not recognise.

Holds the original wire shape so it can be forwarded unchanged. See the module docs for why this is not a shrug.

Implementations

impl Content

pub fn required_features(&self) -> FeatureSet

The features this block needs in order to be expressed.

Empty for Text, Image, EmbeddedResource and Unknown, because all four are expressible at every revision. The rest name the revision that introduced them, and those are exactly the revisions where lowering this block to a 2024-11-05 peer is a downgrade.

pub const fn annotations(&self) -> Option<&Annotations>

The block’s annotations, if it has any.

pub fn type_name(&self) -> &str

The wire type discriminator, for unknown blocks this is the string that was on the wire.

pub const fn kind(&self) -> &'static str

A short label for logs and downgrade messages.

Trait Implementations

impl Clone for Content

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Content

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

Formats the value using the given formatter.

impl Default for Content

fn default() -> Self

An empty text block, which is the only content every revision can express and the only one with a meaningful zero value.

impl PartialEq for Content

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
