Expand description

Trait for contributing display information to tree nodes.

Each extractor represents one “dimension” of display (e.g., nbytes, stats, metadata, buffers). Extractors are composable: you can combine any number of them via TreeDisplay::with.

Provided Methods§

Source

fn write_header( &self, array: &ArrayRef, ctx: &TreeContext, f: &mut Formatter<'_>, ) -> Result

Write header annotations (space-prefixed) to the formatter.

Source

fn write_details( &self, array: &ArrayRef, ctx: &TreeContext, f: &mut IndentedFormatter<'_, '_>, ) -> Result

Write detail lines below the header.

Content written through f is automatically indented. Use f.formatter() to access the underlying fmt::Formatter for formatting flags.
