Struct rustls::RootCertStore

pub struct RootCertStore { /* fields omitted */ }

A container for root certificates able to provide a root-of-trust for connection authentication.

Methods

impl RootCertStore

fn empty() -> RootCertStore

Make a new, empty RootCertStore.

fn is_empty(&self) -> bool

Return true if there are no certificates.

fn len(&self) -> usize

Say how many certificates are in the container.

fn get_subjects(&self) -> DistinguishedNames

Return the Subject Names for certificates in the container.

fn add(&mut self, der: &Certificate) -> Result<(), Error>

Add a single DER-encoded certificate to the store.

fn add_trust_anchors(&mut self, anchors: &[TrustAnchor])

Adds all the given TrustAnchors anchors. This does not fail.

fn add_pem_file(&mut self, rd: &mut BufRead) -> Result<(usize, usize), ()>

Parse a PEM file and add all certificates found inside. Errors are non-specific; they may be io errors in rd and PEM format errors, but not certificate validity errors.

This is because large collections of root certificates often include ancient or syntactictally invalid certificates. CAs are competent like that.

Returns the number of certificates added, and the number which were extracted from the PEM but ultimately unsuitable.
