Struct NoSource 

pub struct NoSource;

A source that answers nothing.

This is what a caller with no install behind it hands in, and it matters more than a convenience type would. Without it a CLI inspecting a loose file would stop at a projection while a GUI with an install reached a resolved view, and the two could not share display code. With it there is one resolved type everywhere, and having no install is a source that declines every question rather than a separate path through the program.

Trait Implementations

impl Clone for NoSource

fn clone(&self) -> NoSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContentSource for NoSource

fn twoda(&mut self, name: impl AsRef<str>) -> Option<&TwoDa>

Returns the named table, or None if it cannot be produced.

fn text(&mut self, strref: StrRef) -> Option<String>

Returns the display text a StrRef names.

fn voiceover(&mut self, strref: StrRef) -> Option<ResRef>

Returns the voiceover resource a StrRef’s entry names.

fn resource_exists( &mut self, resref: &ResRef, resource_type: ResourceTypeCode, ) -> Option<bool>

Returns whether the named resource resolves.

impl Debug for NoSource

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

Formats the value using the given formatter.

impl Default for NoSource

fn default() -> NoSource

Returns the “default value” for a type.

impl Hash for NoSource

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NoSource

fn eq(&self, other: &NoSource) -> 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.
