Struct TransformPluginProgramMetadata
pub struct TransformPluginProgramMetadata {
pub comments: Option<PluginCommentsProxy>,
pub source_map: PluginSourceMapProxy,
pub unresolved_mark: Mark,
}
__common_plugin_transform
or __plugin_transform_host
only.Expand description
An arbitary metadata for given Program to run transform in plugin. These are not directly attached to Program’s AST structures but required for certain transforms.
Fields§
§comments: Option<PluginCommentsProxy>
Proxy to the comments for the Program passed into plugin. This is a proxy to the actual data lives in the host. Only when plugin attempts to read these it’ll ask to the host to get values.
source_map: PluginSourceMapProxy
Proxy to the sourceMap for the Program passed into plugin. This is a proxy to the actual data lives in the host. Only when plugin attempts to read these it’ll ask to the host to get values.
unresolved_mark: Mark
Implementations§
§impl TransformPluginProgramMetadata
impl TransformPluginProgramMetadata
pub fn get_transform_plugin_config(&self) -> Option<String>
Available on crate features __common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.
pub fn get_transform_plugin_config(&self) -> Option<String>
__common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.Returns current plugin’s configuration as a JSON string. Plugin may need to deserialize this string manually.
pub fn get_context(
&self,
key: &TransformPluginMetadataContextKind,
) -> Option<String>
Available on crate features __common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.
pub fn get_context( &self, key: &TransformPluginMetadataContextKind, ) -> Option<String>
__common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.Returns metadata value for given key.
pub fn get_experimental_context(&self, key: &str) -> Option<String>
Available on crate features __common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.
pub fn get_experimental_context(&self, key: &str) -> Option<String>
__common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.Returns an experimental metadata value if exists. Returned value is always a String, but depends on the nature of the metadata it may require additional postprocessing.
Each time this is called, it’ll require a call between host-plugin which involves serialization / deserialization.
Note these metadata values can be changed anytime. There is no gaurantee values will be available across different @swc/core versions.
pub fn get_raw_experimental_context(
&self,
) -> HashMap<String, String, RandomState>
Available on crate features __common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.
pub fn get_raw_experimental_context( &self, ) -> HashMap<String, String, RandomState>
__common_plugin_transform
or __css_plugin_transform
or __ecma_plugin_transform
only.Returns experimental metadata context, but returns whole value as a HashMap.
Each time this is called, it’ll require a call between host-plugin which involves serialization / deserialization.
