Crate xvc_logging

Xvc logging and output crate to be used in output channels. Xvc uses to discriminate outputs of various types, (Info, Debug, Error…) and can use crossbeam_channel to send these separately. Downstream crates (xvc, xvc-file, etc.) use this crate not to use stdout, stderr directly.

Macros

debug

Either send XvcOutputLine::Debug to the given channel, or log via log crate

error

Either send a XvcOutputLine::Error value to the given channel, or log via log crate

info

Either send XvcOutputLine::Info to the given channel, or log via log crate

output

Either send XvcOutputLine::Output to the given channel, or print to stdout

panic

Either send XvcOutputLine::Panic to the given channel, or print to stdout

tick

Either send XvcOutputLine::Tick to the given channel, or print dots to stdout

trace

Either send [XvcOutputLine::Trace] to the given channel, or log via log crate

uwo

Unwrap an option, and if it is an error, send it to the given channel and panic. This is mostly to be used in for_each blocks, where the error is not propagated.

uwr

Unwrap the result of an expression, and if it is an error, send it to the given channel and panic. This is mostly to be used in for_each blocks, where the error is not propagated.

warn

Either send XvcOutputLine::Warn to the given channel, or log via log crate

watch

Debugging macro to print the given expression and its value, with the module, function and line number

Enums

XvcOutputLine

Different channels of outputs Xvc can print
