pub const GLOBAL_LAYER: &str = "global";Expand description
The name of the layer built from the top-level [keys] table.
It is the one name this crate assigns: the bare [keys] table (and an
explicit [layers.global], if present) build the layer under this key, which
is always present in BuildOutput::layers even when empty. Every other
layer name is opaque to the library — it is just the label the config author
chose; the library attaches no meaning to it and never decides when a layer is
active. That selection stays caller-side (see keymap_core::resolve_layered).
