Struct DebugDisplay 

pub struct DebugDisplay<'value, T: ?Sized> { /* private fields */ }

Presents a borrowed fmt::Debug value through fmt::Display.

This adapter performs no eager allocation or formatting. Passing it to crate::Redactor::redact_field or crate::RedactedTextComposer::field lets an opaque high- or secret-sensitivity mask avoid observing the wrapped value altogether. The wrapped Debug implementation runs only when the selected policy needs the source representation, such as for pass-through, disabled, low-, or medium-sensitivity rendering.

Type Parameters

• 'value: Lifetime of the borrowed source.
• T: Source type; its Debug implementation is required when formatting.

Examples

use qubit_redact::{DebugDisplay, Redactor};

let values = vec!["first", "second"];
let output = Redactor::strict().redact_field("selection", &DebugDisplay::new(&values));
assert_eq!(output.text().as_str(), "<redacted>");

Implementations

impl<'value, T: ?Sized> DebugDisplay<'value, T>

pub const fn new(value: &'value T) -> Self

Wraps a borrowed value without formatting or allocating.

Parameters

• value: Source whose Debug formatter is deferred until needed.

Returns

A borrowed adapter that has not inspected or formatted the source.

Trait Implementations

impl<'value, T: Clone + ?Sized> Clone for DebugDisplay<'value, T>

fn clone(&self) -> DebugDisplay<'value, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'value, T: Copy + ?Sized> Copy for DebugDisplay<'value, T>

impl<T> Display for DebugDisplay<'_, T>

where T: Debug + ?Sized,

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Lazily delegates formatting to the wrapped value’s Debug output.

Parameters

• formatter: Destination formatter receiving the source Debug representation.

Returns

Success after the wrapped Debug formatter completes.

Errors

Propagates any error returned by the wrapped Debug implementation or destination.
