Struct MessageManager 

pub struct MessageManager {
    defs: Vec<MessageDef>,
    slot_to_index: HashMap<u32, usize>,
    active: Vec<ActiveMessage>,
    cycle_cursor: usize,
    transient_default: MessageDef,
}

Message system: definitions + active instances + cycle cursor.

Fields

defs: Vec<MessageDef>

slot_to_index: HashMap<u32, usize>

active: Vec<ActiveMessage>

cycle_cursor: usize

Cursor for the T keybind. Walks the defs vec mod len.

transient_default: MessageDef

Fallback styling used by Self::show_transient when no MILK_MSG.INI is loaded. Centred, white, 32 px, 0.5 s fade-in / fade-out, 4 s sustain.

Implementations

impl MessageManager

pub fn new() -> Self

pub fn load_defs(&mut self, defs: Vec<MessageDef>)

Load a freshly-parsed set of message definitions, replacing any previous load. Doesn’t touch the active list.

pub fn def_count(&self) -> usize

pub fn active_count(&self) -> usize

pub fn spawn_slot(&mut self, slot: u32, time: f32) -> bool

Spawn a message by INI slot at time. Multiple spawns of the same slot stack — matches the sprite manager + MD2 behaviour.

pub fn cycle_next(&mut self, time: f32) -> Option<u32>

T keybind: cycle to the next loaded slot.

pub fn clear(&mut self)

Drop every active message (Ctrl+Y keybind).

pub fn show_transient(&mut self, text: impl Into<String>, time: f32)

Show a transient message — used by the MPRIS auto-title path. Reuses the first loaded def’s style (font, size, colour, position, fade timing) so user-authored typography sticks; if no def is loaded, the built-in transient_default is used. The text argument overrides the def’s text= field.

pub fn tick(&mut self, time: f32) -> Vec<MessageRenderInstance>

Advance every active message by one tick at engine time time. Returns the list of MessageRenderInstances for the renderer, sorted in spawn order so later messages paint over earlier ones.

Trait Implementations

impl Default for MessageManager

fn default() -> Self

Returns the “default value” for a type.
