encoding: Option<String>

encryption: Option<String>

encryption_key: Option<String>

crypto_key: Option<String>

Implementations

impl NotificationHeaders

pub fn from_request(req: &HttpRequest, has_data: bool) -> Result<Self, ApiError>

Extract the notification headers from a request. This can not be implemented as a FromRequest impl because we need to know if the payload has data, without actually advancing the payload stream.

fn strip_header(header: String) -> String

Remove Base64 padding and double-quotes

fn validate_encryption(&self) -> Result<(), ApiError>

Validate the encryption headers according to the various WebPush standard versions

fn validate_encryption_04_rules(&self) -> Result<(), ApiError>

Validates encryption headers according to draft-ietf-webpush-encryption-04

fn validate_encryption_06_rules(&self) -> Result<(), ApiError>

Validates encryption headers according to draft-ietf-httpbis-encryption-encoding-06 (the encryption values are in the payload, so there shouldn’t be any in the headers)

fn assert_base64_item_exists( header_name: &str, header: Option<&str>, key: &str, ) -> Result<(), ApiError>

Assert that the given item exists in the header and is valid base64.

fn assert_not_exists( header_name: &str, header: Option<&str>, key: &str, ) -> Result<(), ApiError>

Assert that the given key does not exist in the header.

Trait Implementations

impl Clone for NotificationHeaders

fn clone(&self) -> NotificationHeaders

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NotificationHeaders

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

Formats the value using the given formatter.

impl From<NotificationHeaders> for HashMap<String, String>

fn from(headers: NotificationHeaders) -> Self

Converts to this type from the input type.

impl PartialEq for NotificationHeaders

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Validate for NotificationHeaders

fn validate(&self) -> Result<(), ValidationErrors>

impl<'v_a> ValidateArgs<'v_a> for NotificationHeaders

type Args = ()

fn validate_with_args(&self, args: Self::Args) -> Result<(), ValidationErrors>

impl Eq for NotificationHeaders
