Struct LayoutLibrary 

pub struct LayoutLibrary { /* private fields */ }

Named layouts per view id, for “Save Layout As…” and a layout picker, plus the layout each view opens with.

Plain data: the application stores it where it keeps its settings and serializes it with serde. A view id names the kind of grid (“trades”), not a panel: every panel of a view shares its layouts. Layouts are kept as given; the grid checks their version when it applies one.

Implementations

impl LayoutLibrary

pub fn new() -> Self

An empty library.

pub fn insert( &mut self, name: impl Into<String>, layout: GridLayout, ) -> Result<(), LayoutError>

Stores layout under its view id and name, replacing a layout with that name. Fails with LayoutError::MissingViewId if the layout has no view id.

pub fn get(&self, view_id: &str, name: &str) -> Option<&GridLayout>

The layout of a view with this name.

pub fn names<'a>( &'a self, view_id: &str, ) -> impl Iterator<Item = &'a str> + use<'a>

The names of a view’s layouts, sorted by their text (byte order).

pub fn remove(&mut self, view_id: &str, name: &str) -> Option<GridLayout>

Removes a layout. If it was the view’s default, the view has no default afterwards.

pub fn rename( &mut self, view_id: &str, from: &str, to: impl Into<String>, ) -> bool

Renames a layout; the default follows it. Returns false, and changes nothing, if there is no layout from or another layout is named to.

pub fn set_default(&mut self, view_id: &str, name: Option<&str>) -> bool

Sets the layout a view opens with when nothing else is restored, or clears it with None. Returns false, and changes nothing, if the view has no layout with that name.

pub fn default_layout(&self, view_id: &str) -> Option<(&str, &GridLayout)>

The name and layout a view opens with when nothing else is restored.

Trait Implementations

impl Clone for LayoutLibrary

fn clone(&self) -> LayoutLibrary

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LayoutLibrary

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LayoutLibrary

fn default() -> LayoutLibrary

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LayoutLibrary

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LayoutLibrary

fn eq(&self, other: &LayoutLibrary) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LayoutLibrary

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
