Enum edge_schema::schema::CgiDialect

pub enum CgiDialect {
    Rfc3875,
    Wcgi,
}

The CGI dialect to use when running a CGI workload.

Variants

Rfc3875

The “official” CGI dialect, as defined by RFC 3875.

Wcgi

Implementations

impl CgiDialect

pub const CUSTOM_SECTION_NAME: &str = "cgi-dialect"

pub fn from_wasm(wasm: &[u8]) -> Option<CgiDialect>

Try to identify which CgiDialect should be used based on the WebAssembly module’s binary representation.

Implementation Notes

This currently works by looking through the WebAssembly binary for a custom section called CgiDialect::CUSTOM_SECTION_NAME and matching it against one of the known CGI dialects.

This whole process is kinda hacky because it means you need to alter your binary to include the custom section. In the future, the CGI dialect should be specified using some external mechanism like metadata.

pub fn prepare_environment_variables( self, parts: Parts, env: &mut HashMap<String, String> )

pub async fn extract_response_header( self, stdout: &mut (impl AsyncBufRead + Unpin) ) -> Result<Parts, CgiError>

Extract the http::response::Parts from a CGI script’s stdout.

Note

This might stall if reading from stdout stalls. Care should be taken to avoid waiting forever (e.g. by adding a timeout).

pub const fn to_str(self) -> &'static str

Trait Implementations

impl Clone for CgiDialect

fn clone(&self) -> CgiDialect

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CgiDialect

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

Formats the value using the given formatter.

impl Default for CgiDialect

fn default() -> CgiDialect

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CgiDialect

fn deserialize<__D>( __deserializer: __D ) -> Result<CgiDialect, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CgiDialect

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

Formats the value using the given formatter.

impl FromStr for CgiDialect

type Err = UnknownCgiDialect

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<CgiDialect, <CgiDialect as FromStr>::Err>

Parses a string s to return a value of this type.

impl JsonSchema for CgiDialect

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for CgiDialect

fn eq(&self, other: &CgiDialect) -> 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.

impl Serialize for CgiDialect

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CgiDialect

impl Eq for CgiDialect
