Modern Log LogEvent AddError

Home › Logging › Logging › LogEvent.AddError

LogEvent.AddError

Adds a filesystem error as fields: its message, its code and any system error code.

Syntax

AddError( v as FsError )

Notes

• expands to error, error.code and error.os

Examples

#import "std/fs"
#import "std/containers"
#import "std/outcome"
#import "std/numeric"
#import "std/logs"
using logs, fs, containers, outcome, numeric


dim con as ConsoleSink
dim lg as Logger
lg.AddSink( @con )

'' One call expands to THREE fields -- the message, the code and the OS
'' error -- so a filesystem failure is logged the same way every time
'' FsError's fields are read-only accessors -- Code( ), OsCode( ),
'' Path( ) -- so one is built through its constructor, not assigned to
dim e as FsError = FsError( FS_NOT_FOUND, 2, "CreateFileW", "data.csv" )
lg.Error( ).AddError( e ).Msg( "open failed" )
