Struct deno_core::ModuleSource

pub struct ModuleSource {
    pub code: ModuleSourceCode,
    pub module_type: ModuleType,
    pub code_cache: Option<Cow<'static, [u8]>>,
    /* private fields */
}

EsModule source code that will be loaded into V8.

Users can implement Into<ModuleInfo> for different file types that can be transpiled to valid EsModule.

Found module URL might be different from specified URL used for loading due to redirections (like HTTP 303). Eg. Both “https://example.com/a.ts” and “https://example.com/b.ts” may point to “https://example.com/c.ts” By keeping track of specified and found URL we can alias modules and avoid recompiling the same code 3 times.

Fields

code: ModuleSourceCode

module_type: ModuleType

code_cache: Option<Cow<'static, [u8]>>

Implementations

impl ModuleSource

pub fn new( module_type: impl Into<ModuleType>, code: ModuleSourceCode, specifier: &ModuleSpecifier, code_cache: Option<Cow<'static, [u8]>> ) -> Self

Create a ModuleSource without a redirect.

pub fn new_with_redirect( module_type: impl Into<ModuleType>, code: ModuleSourceCode, specifier: &ModuleSpecifier, specifier_found: &ModuleSpecifier, code_cache: Option<Cow<'static, [u8]>> ) -> Self

Create a ModuleSource with a potential redirect. If the specifier_found parameter is the same as the specifier, the code behaves the same was as ModuleSource::new.

pub fn get_string_source( specifier: &str, code: ModuleSourceCode ) -> Result<ModuleCodeString, AnyError>

Trait Implementations

impl Debug for ModuleSource

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

Formats the value using the given formatter.
