Struct FixedLengthFileWriterBuilder

pub struct FixedLengthFileWriterBuilder { /* private fields */ }

A helper struct for building an instance of a FixedLengthFileWriter struct.

Implementations

impl FixedLengthFileWriterBuilder

pub fn with_out_path(self, out_path: PathBuf) -> Self

Set the relative or absolute path to write the fixed-length file (.flf) to.

pub fn with_properties( self, properties: FixedLengthFileWriterProperties, ) -> Self

Set the properties to use when opening the file descriptor.

pub fn try_build(self) -> Result<FixedLengthFileWriter>

Try creating a new FixedLengthFileWriter from the previously set values.

Errors

If any of the required fields have not been set and thus are None, or if the properties contained an invalid combination of settings. See OpenOptions documentation for details on all errors it can return.

pub fn build(self) -> FixedLengthFileWriter

Creates a new FixedLengthFileWriter from the previously set values.

Note

This method internally calls the try_build method and simply unwraps the returned Result. If you don’t care about error propagation, use this method over try_build.

Panics

If any of the required fields have not been set and thus are None, or if the properties contained an invalid combination of settings.
