Struct DebugPrefix

pub struct DebugPrefix { /* private fields */ }

Debug prefix.

Utility for implementing multi-line Debuggable output in a nested horizontal tree-like structure.

Implementations

impl DebugPrefix

pub fn new(style: Style) -> Self

Constructor.

pub fn with(&self, suffix: &str) -> Self

Clone and add a custom suffix.

pub fn with_branch(&self, last: bool) -> Self

Clone and add a branch-style suffix.

pub fn with_thick_branch(&self, last: bool) -> Self

Clone and add a thick branch-style suffix.

pub fn with_double_branch(&self, last: bool) -> Self

Clone and add a double branch-style suffix.

pub fn write<WriteT>(&self, writer: &mut WriteT) -> Result<()>

where WriteT: Write,

Write a newline plus this prefix.

pub fn conditional_write<WriteT>( &self, writer: &mut WriteT, first: bool, ) -> Result<()>

where WriteT: Write,

If first is false, write a newline plus this prefix.

pub fn write_with<WriteT>( &self, writer: &mut WriteT, suffix: &str, ) -> Result<()>

where WriteT: Write,

Write a newline plus this prefix. Then write a custom suffix.

pub fn conditional_write_with<WriteT>( &self, writer: &mut WriteT, suffix: &str, first: bool, ) -> Result<()>

where WriteT: Write,

If first is false, write a newline plus this prefix. Then write a custom suffix. The custom suffix is always written.

pub fn write_with_branch<WriteT>( &self, writer: &mut WriteT, last: bool, ) -> Result<()>

where WriteT: Write,

Write a newline plus this prefix plus a branch-style suffix.

pub fn write_with_thick_branch<WriteT>( &self, writer: &mut WriteT, last: bool, ) -> Result<()>

where WriteT: Write,

Write a newline plus this prefix plus a thick branch-style suffix.

pub fn write_with_double_branch<WriteT>( &self, writer: &mut WriteT, last: bool, ) -> Result<()>

where WriteT: Write,

Write a newline plus this prefix plus a double branch-style suffix.
