Struct CspNonce 

pub struct CspNonce(/* private fields */);

A cryptographically random CSP nonce associated with one request.

Handlers and renderers can extract this value with Extension<CspNonce> and add nonce="..." to trusted inline <script> or <style> elements.

Implementations

impl CspNonce

pub fn generate() -> Self

Generates a fresh 128-bit nonce using the operating system random source.

pub fn as_str(&self) -> &str

Returns the nonce value for an HTML nonce attribute.

pub fn get_or_insert(extensions: &mut Extensions) -> Self

Returns the nonce already associated with a request or creates and stores a fresh one.

Security layers should use this helper instead of unconditionally replacing the request extension so independently composed layers and the renderer share one nonce identity.
