pub struct BlockNoteWriter<'a, W>
where
    W: Write,
{ /* private fields */ }

Available on crate feature blocknote only.

Streaming BlockNote JSON writer. Available when the blocknote feature is enabled. A streaming BlockNote JSON writer.

Writes JSON tokens directly to the underlying Write as events arrive using docspec-json. Implements EventSink for integration with the DocSpec pipeline.

Use BlockNoteWriter::with_assets to provide an AssetProvider for resolving embedded asset images as base64 data URIs.

Type Parameters

• W - Any type implementing Write

Implementations

impl<'a, W> BlockNoteWriter<'a, W>

where W: Write,

pub fn new(writer: W) -> BlockNoteWriter<'a, W>

Creates a new BlockNoteWriter that writes to the given writer.

Arguments

• writer - The underlying writer to emit JSON to

pub fn with_assets( writer: W, assets: &'a dyn AssetProvider, ) -> BlockNoteWriter<'a, W>

Creates a new BlockNoteWriter with an AssetProvider for resolving embedded assets.

When an Event::Image with ImageSource::Asset is encountered, the provider is called to resolve the asset bytes. The bytes are base64-encoded and written as a data URI (data:{content_type};base64,{encoded}) in the BlockNote JSON url field.

Arguments

• writer - The underlying writer to emit JSON to
• assets - The asset provider for resolving embedded asset references
