Struct DynamicContextBuilder

pub struct DynamicContextBuilder<'a> { /* private fields */ }

A builder for constructing a DynamicContext.

This needs to be supplied a [StaticContext] (or a reference to one) in order to construct it.

You can supply a context item, documents, variables and the like in order to construct a dynamic context used to execute an XPath instruction.

Implementations

impl<'a> DynamicContextBuilder<'a>

pub fn context_item(&mut self, context_item: Item) -> &mut Self

Set the context item of the DynamicContext.

Without this, the DynamicContext will have no context item.

pub fn context_node(&mut self, node: Node) -> &mut Self

Set a node as the context item of the DynamicContext.

pub fn documents(&mut self, documents: impl Into<DocumentsRef>) -> &mut Self

Set the documents of the DynamicContext.

You can give it either owned documents or a DocumentsRef.

pub fn variables(&mut self, variables: Variables) -> &mut Self

Set the variables of the DynamicContext.

Without this, the DynamicContext will have no variables.

pub fn current_datetime( &mut self, current_datetime: DateTime<FixedOffset>, ) -> &mut Self

Set the current datetime of the DynamicContext.

Without this, the DynamicContext will have the current datetime.

pub fn default_collection(&mut self, sequence: Sequence) -> &mut Self

Set the default collection

pub fn collection(&mut self, uri: &IriStr, sequence: Sequence) -> &mut Self

Set a collection

pub fn default_uri_collection(&mut self, uris: &[&IriStr]) -> &mut Self

Set the default URI collection

pub fn uri_collection(&mut self, uri: &IriStr, uris: &[&IriStr]) -> &mut Self

Set a URI collection

pub fn environment_variables( &mut self, environment_variables: HashMap<String, String>, ) -> &mut Self

Set the environment variables

pub fn initialize_env(&mut self) -> &mut Self

Initialize the environment variables from the current system environment.

pub fn build(&self) -> DynamicContext<'_>

Build the DynamicContext.

Trait Implementations

impl<'a> Clone for DynamicContextBuilder<'a>

fn clone(&self) -> DynamicContextBuilder<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DynamicContextBuilder<'a>

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