Struct otter_nodejs_tests::otter_support::crates::flexi_logger::FileSpec

pub struct FileSpec { /* private fields */ }

Builder object for specifying the name and path of the log output file.

assert_eq!(
    FileSpec::default()
        .directory("/a/b/c")
        .basename("foo")
        .suppress_timestamp()
        .suffix("bar"),

);

Implementations

impl FileSpec

pub fn try_from<P>(p: P) -> Result<FileSpec, FlexiLoggerError> where
    P: Into<PathBuf>, 

The provided path should describe a log file. If it exists, it must be a file, not a folder. If necessary, parent folders will be created.

Errors

FlexiLoggerError::OutputBadFile if the given path exists and is a folder.

Panics

Panics if the basename of the given path has no filename

pub fn basename<S>(self, basename: S) -> FileSpec where
    S: Into<String>, 

The specified String is used as the basename of the log file name, instead of the program name. Using a file separator within the argument is discouraged.

pub fn o_basename<S>(self, o_basename: Option<S>) -> FileSpec where
    S: Into<String>, 

The specified String is used as the basename of the log file, instead of the program name, which is used when None is given.

pub fn directory<P>(self, directory: P) -> FileSpec where
    P: Into<PathBuf>, 

Specifies a folder for the log files.

If the specified folder does not exist, it will be created. By default, the log files are created in the folder where the program was started.

pub fn o_directory<P>(self, directory: Option<P>) -> FileSpec where
    P: Into<PathBuf>, 

Specifies a folder for the log files.

If the specified folder does not exist, it will be created. With None, the log files are created in the folder where the program was started.

pub fn discriminant<S>(self, discriminant: S) -> FileSpec where
    S: Into<String>, 

The specified String is added to the log file name.

pub fn o_discriminant<S>(self, o_discriminant: Option<S>) -> FileSpec where
    S: Into<String>, 

The specified String is added to the log file name.

pub fn suffix<S>(self, suffix: S) -> FileSpec where
    S: Into<String>, 

Specifies a suffix for the log files.

Equivalent to o_suffix(Some(suffix)).

pub fn o_suffix<S>(self, o_suffix: Option<S>) -> FileSpec where
    S: Into<String>, 

Specifies a suffix for the log files, or supresses the use of a suffix completely.

The default suffix is “log”.

pub fn suppress_timestamp(self) -> FileSpec

Makes the logger not include a timestamp into the names of the log files

Equivalent to use_timestamp(false).

pub fn use_timestamp(self, use_timestamp: bool) -> FileSpec

Defines if a timestamp should be included into the names of the log files.

The default behavior depends on the usage:

• without rotation, a timestamp is by default included into the name
• with rotation, the timestamp is by default suppressed

pub fn as_pathbuf(&self, o_infix: Option<&str>) -> PathBuf

Creates a PathBuf to the described log file.

It is composed like this: <directory>/<basename>_<discr>_<timestamp><infix>.<suffix>

Trait Implementations

impl Clone for FileSpec

fn clone(&self) -> FileSpec

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FileSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl Default for FileSpec

fn default() -> FileSpec
