Struct InMemorySys 

pub struct InMemorySys(/* private fields */);

An in-memory system implementation useful for testing.

This is extremely untested and sloppily implemented. Use with extreme caution and only for testing. You will encounter bugs. Please submit fixes. I implemented this lazily and quickly.

Implementations

impl InMemorySys

pub fn new_with_cwd(cwd: impl AsRef<Path>) -> Self

pub fn set_seed(&self, seed: Option<u64>)

pub fn set_time(&self, time: Option<SystemTime>)

pub fn disable_thread_sleep(&self)

Makes thread sleeping a no-op.

pub fn fs_insert(&self, path: impl AsRef<Path>, data: impl AsRef<[u8]>)

pub fn fs_insert_json(&self, path: impl AsRef<Path>, json: Value)

Helper method for inserting json into the in-memory file system.
