Struct RedactionRule 

pub struct RedactionRule<'a> {
    pub pattern: &'a str,
    pub limit: usize,
    pub replacement: &'a str,
}

A rule specifying how to redact data matching a specific regular expression pattern.

Rules consist of a regex pattern, a replacement string (supporting regex capture groups such as $1), and a maximum replacement limit.

Examples

use assert_snap::redaction::RedactionRule;
let rule = RedactionRule::new(r"token_\w+", "[REDACTED]", 1);

Fields

pattern: &'a str

The regular expression pattern to match.

limit: usize

The maximum number of replacements to make. If 0, all occurrences are replaced.

replacement: &'a str

The replacement template (supports regex capture groups like $1).

Implementations

impl<'a> RedactionRule<'a>

pub fn new(pattern: &'a str, replacement: &'a str, limit: usize) -> Self

Creates a new redaction rule.

Arguments

• pattern - The regular expression pattern to match against the input data.
• replacement - The replacement template. Supports capture group references like $1, $2, etc.
• limit - The maximum number of replacements to make. If 0, all occurrences are replaced.

Returns

A new RedactionRule instance.
