Derive Macro NotSensitiveDisplay 

#[derive(NotSensitiveDisplay)]

Derives redactable::RedactableWithFormatter for types with no sensitive data.

This is the display counterpart to NotSensitive. Use it when you have a type with no sensitive data that needs logging integration (e.g., for use with slog).

Unlike SensitiveDisplay, this derive does not require a display template. Instead, it delegates directly to the type’s existing Display implementation.

Required Bounds

The type must implement Display. This is required because RedactableWithFormatter delegates to Display::fmt.

Generated Impls

• RedactableWithMapper: no-op passthrough (allows use inside Sensitive containers)
• RedactableWithFormatter: delegates to Display::fmt
• slog::Value and SlogRedacted (behind cfg(feature = "slog")): uses RedactableWithFormatter output
• TracingRedacted (behind cfg(feature = "tracing")): marker trait

Debug

NotSensitiveDisplay does not generate a Debug impl - there’s nothing to redact. Use #[derive(Debug)] alongside NotSensitiveDisplay when needed:

Rejected Attributes

#[sensitive] and #[not_sensitive] attributes are rejected on both the container and its fields - the former is wrong (the type is explicitly non-sensitive), the latter is redundant (the entire type is already non-sensitive).

Example

use redactable::NotSensitiveDisplay;

#[derive(Clone, NotSensitiveDisplay)]
#[display(fmt = "RetryDecision")]  // Or use displaydoc/thiserror for Display impl
enum RetryDecision {
    Retry,
    Abort,
}
