Struct artichoke_backend::load_path::Rubylib[][src]

pub struct Rubylib { /* fields omitted */ }

Implementations

Create a new native virtual filesystem that searches the filesystem for Ruby sources at the paths specified by the RUBYLIB environment variable.

This filesystem grants access to the host filesystem.

Check whether path points to a file in the virtual filesystem and return the absolute path if it exists.

This API is infallible and will return None for non-existent paths.

Check whether path points to a file in the virtual filesystem.

This API is infallible and will return false for non-existent paths.

Read file contents for the file at path.

Returns a byte slice of complete file contents. If path is relative, it is absolutized relative to the current working directory of the virtual file system.

Errors

If path does not exist, an io::Error with error kind io::ErrorKind::NotFound is returned.

Check whether a file at path has been required already.

This API is infallible and will return false for non-existent paths.

Mark a source at path as required on the interpreter.

This metadata is used by Kernel#require and friends to enforce that Ruby sources are only loaded into the interpreter once to limit side effects.

Errors

If path does not exist, an io::Error with error kind io::ErrorKind::NotFound is returned.
