Remove

Fields

node_id: u32

SetText

Fields

node_id: u32

text: &'a str

selection: Option<Selection>

AppendText

Appends the streamed tail to a Text node instead of resending the whole string.

Fields

node_id: u32

text: &'a str

SetTheme(Theme)

The root theme. Sent once as the first record of the initial batch.

SetWindow(Window)

What the application asked of its own window.

Written once per rebuild beside the theme, and read by the Renderer before it stands the window up: dioxus_compose_host_init answers with the first batch, so the setting is in hand before there is a window to apply it to. Platforms where the window is not ours ignore it, which is not an error but an absence of anywhere to put it.

RegisterAsset

Hands the Renderer the bytes of one asset. The Renderer copies them into its own cache inside this call, because the batch buffer is only valid for the call that carries it and an image has to outlive the frame that draws it.

Fields

asset_id: u32

kind: AssetKind

bytes: &'a [u8]

ReleaseAsset

Drops an asset from the Renderer’s cache. The Host owns the lifetime.

Fields

asset_id: u32

ShowMessage

Says a sentence to the user once. It is not a node, because the Host would then have to hold “showing until four seconds from now” and run a render to take it away again. How long it stays, where it sits and what happens when a second one arrives while the first is up are all the Renderer’s.

handler_id is what the action label reports when it is pressed, or 0 when the message has no action, in which case action is empty too.

Fields

handler_id: u64

text: &'a str

action: &'a str

duration: MessageDuration
