Struct Layers 

pub struct Layers {
    pub index: bool,
    pub colours: bool,
    pub attachments: bool,
}

Which layers are on. Every one is off by default and turned on by name.

let layers = Layers::none().with_index().with_colours();
assert!(layers.index && layers.colours && !layers.attachments);

Fields

index: bool

The package index.

colours: bool

The colour walks (derived from the index).

attachments: bool

The attachment listings (derived from the index).

Implementations

impl Layers

pub const fn none() -> Self

Nothing on.

pub const fn all() -> Self

Every layer there is - what a long-lived session wants.

pub const fn with_index(self) -> Self

Turn the index on.

pub const fn with_colours(self) -> Self

Turn the colour walks on.

pub const fn with_attachments(self) -> Self

Turn the attachment listings on.

pub const fn normalised(self) -> Self

The layers with what they stand on turned on too: a layer derived from the index has no index to be exact for when the index is off.
