Implementations

impl MmapUnifiedLoggerBuilder

pub fn new() -> Self

pub fn file_base_name(self, file_path: &Path) -> Self

If “something/toto.copper” is given, it will find or create “something/toto_0.copper”, “something/toto_1.copper” etc.

pub fn preallocated_size(self, preallocated_size: usize) -> Self

pub fn write(self, write: bool) -> Self

pub fn create(self, create: bool) -> Self

pub fn append(self, append: bool) -> Self

When write and create are both set, resume writing at the end of an existing log instead of truncating it.

Requires a cleanly closed log (one ending with a permanent end-of-log marker). Returns an error if the log does not exist or is incomplete.

pub fn build(self) -> Result<MmapUnifiedLogger>
