* `warn!(...)` - a macro hard-wired to the log level of `WARN`
* `error!(...)` - a macro hard-wired to the log level of `ERROR`
-All of these macros use std::the same style of syntax as the `format!` syntax
+All of these macros use the same style of syntax as the `format!` syntax
extension. Details about the syntax can be found in the documentation of
`std::fmt` along with the Rust tutorial/manual.
If you want to check at runtime if a given logging level is enabled (e.g. if the
-information you would want to log is expensive to produce), you can use std::the
+information you would want to log is expensive to produce), you can use the
following macro:
* `log_enabled!(level)` - returns true if logging of the given level is enabled
The path to the module is rooted in the name of the crate it was compiled for,
so if your program is contained in a file `hello.rs`, for example, to turn on
-logging for this file you would use std::a value of `RUST_LOG=hello`.
+logging for this file you would use a value of `RUST_LOG=hello`.
Furthermore, this path is a prefix-search, so all modules nested in the
specified module will also have logging enabled.
