Module cradle::output [−][src]
Expand description
The Output trait that defines all possible outputs of a child process.
Structs
Use Status as the return type for run_output! to retrieve the
ExitStatus of the child process:
Stderr allows to capture the stderr of a child process:
Returns what the child process writes to stdout, interpreted as utf-8,
collected into a string, trimmed of leading and trailing whitespace.
This also suppresses output of the child’s stdout
to the parent’s stdout. (Which would be the default when not using StdoutTrimmed
as the return value.)
Same as StdoutTrimmed, but does not trim whitespace from the output:
Traits
All possible return types of run!, run_output! or
run_result! must implement this trait.
This return-type polymorphism makes cradle very flexible.
For example, if you want to capture what a command writes
to stdout you can do that using StdoutUntrimmed:
