Struct slog::Record
[−]
[src]
pub struct Record<'a> { /* fields omitted */ }One logging record
Corresponds to one logging statement like info!(...) and carries all it's
data: eg. message, immediate key-value pairs and key-value pairs of Logger
used to execute it.
Record is passed to a Logger, which delivers it to it's own Drain,
where actual logging processing is implemented.
Methods
impl<'a> Record<'a>[src]
fn msg(&self) -> &Arguments
Get a log record message
fn level(&self) -> Level
Get record logging level
fn line(&self) -> u32
Get line number
fn location(&self) -> &RecordLocation
Get line number
fn column(&self) -> u32
Get error column
fn file(&self) -> &'static str
Get file path
fn tag(&self) -> &str
Get tag
Tag is information that can be attached to Record that is not meant
to be part of the norma key-value pairs, but only as an ad-hoc control
flag for quick lookup in the Drains. As such should be used carefully
and mostly in application code (as opposed to libraries) - where tag
meaning across the system can be coordinated. When used in libraries,
make sure to prefix is with something reasonably distinct, like create
name.
fn module(&self) -> &'static str
Get module
fn function(&self) -> &'static str
Get function (placeholder)
There's currently no way to obtain that information in Rust at compile time, so it is not implemented.
It will be implemented at first opportunity, and it will not be considered a breaking change.
fn kv(&self) -> BorrowedKV
Get key-value pairs
