Struct snapbox::filter::Redactions

pub struct Redactions { /* private fields */ }

Match pattern expressions, see Assert

Built-in placeholders:

• ... on a line of its own: match multiple complete lines
• [..]: match multiple characters within a line

Implementations

impl Redactions

pub fn new() -> Self

pub fn insert( &mut self, placeholder: &'static str, value: impl Into<RedactedValue> ) -> Result<()>

Insert an additional match pattern

placeholder must be enclosed in [ and ].

let mut subst = snapbox::Redactions::new();
subst.insert("[EXE]", std::env::consts::EXE_SUFFIX);

pub fn extend( &mut self, vars: impl IntoIterator<Item = (&'static str, impl Into<RedactedValue>)> ) -> Result<()>

Insert additional match patterns

placeholders must be enclosed in [ and ].

pub fn remove(&mut self, placeholder: &'static str) -> Result<()>

pub fn normalize(&self, input: &str, pattern: &str) -> String

Apply match pattern to input

If pattern matches input, then pattern is returned.

Otherwise, input, with as many patterns replaced as possible, will be returned.

let subst = snapbox::Redactions::new();
let output = subst.normalize("Hello World!", "Hello [..]!");
assert_eq!(output, "Hello [..]!");

Trait Implementations

impl Clone for Redactions

fn clone(&self) -> Redactions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Redactions

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

Formats the value using the given formatter.

impl Default for Redactions

fn default() -> Redactions

Returns the “default value” for a type.

impl PartialEq for Redactions

fn eq(&self, other: &Redactions) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
