Crate cap_async_std
source · [−]Expand description
A capability-based API modeled after async_std
.
This corresponds to async_std
.
Capability-based APIs represent access to external resources as values which can be passed around between different parts of a program.
Two notable features are the Dir
and Pool
types:
Dir
represents an open directory in a filesystem. Instead of opening files by absolute paths or paths relative to the current working directory, files are opened via paths relative to aDir
. The concepts of a process-wide “current working directory” and a single global filesystem namespace are de-emphasized.Pool
represents a set of network addresses. Instead of allowing applications to request access to any address and then applying process-wide filtering rules, filtering rules are built into pools which may be passed through the program.
On WASI, use of this library closely reflects the underlying system API, so it avoids compatibility layers.

Instances of this
AmbientAuthority
type serve to indicate that the
ambient_authority
function has been called, indicating that the user
has explicitly opted into using ambient authority.Functions
Return an
AmbientAuthority
value, which allows use of functions that
include an AmbientAuthority
argument.
