Struct MemSource 

pub struct MemSource {
    pub caps: SourceCapabilities,
    pub files: BTreeMap<String, String>,
    pub log: Vec<(&'static str, String, String)>,
    /* private fields */
}

An in-memory source for tests: a path → content map with a configurable capability set; writes and removes are applied to the map and logged.

Fields

caps: SourceCapabilities

files: BTreeMap<String, String>

log: Vec<(&'static str, String, String)>

("write", path, content) / ("remove", path, "") in call order.

Implementations

impl MemSource

pub fn new(caps: SourceCapabilities) -> Self

pub fn with_files(files: &[(&str, &str)]) -> Self

A source with path → content files and every capability.

pub fn set(&mut self, path: &str, content: &str)

Set a file from “outside” (as if the human edited it).

pub fn emit(&self, paths: &[&str])

Emit a watch batch (a no-op when nothing watches).

Trait Implementations

impl Debug for MemSource

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

Formats the value using the given formatter.

impl Default for MemSource

fn default() -> Self

Returns the “default value” for a type.

impl SyncSource for MemSource

fn capabilities(&self) -> SourceCapabilities

fn enumerate(&mut self) -> Result<Vec<SourceEntry>>

The full current scope.

fn fetch(&mut self, path: &str) -> Result<Option<SourceItem>>

One member’s current state, or None when it left the scope.

fn write(&mut self, path: &str, content: &str) -> Result<()>

Persist engine-authored bytes (write-through sources only).

fn remove(&mut self, path: &str) -> Result<()>

Remove a member (write-through sources only).

fn watch(&mut self) -> Result<Receiver<Vec<String>>>

Subscribe to change batches: each received value is one batch of changed paths (watching sources only).

fn unwatch(&mut self) -> Result<()>

Stop the batches.

fn close(&mut self) -> Result<()>

Release the process / resources.
