Struct Target

pub struct Target {}

Expand description

Helper for building a target for flushing data into.

Implementations§

impl Target

pub fn from_column(name: &str) -> ColumnTarget

Write output to a file whose path is specified by the given column.

This gives the oportunity to create a stream that writes to multiple files depending on some criteria. It doesn’t write the value of the specified column by default, it is just used to decide the path to the file(s) for writing but that behaviour is configurable.

pub fn path(path: &str) -> impl TargetManager

Write output to the specified path in the filesystem.

pub fn stdout() -> impl TargetManager

Write output to stdout

pub fn stderr() -> impl TargetManager

Write output to stderr

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error
