Struct DataSourceContext 

pub struct DataSourceContext { /* private fields */ }

DataSourceContext — per-instance configuration passed via createWithContext. Mirrors graph-ts DataSourceContext: typed key-value store.

Implementations

impl DataSourceContext

pub fn empty() -> Self

Create a new empty context (for write-side construction).

pub fn new(fields: HashMap<String, Value>) -> Self

Create a context from an existing field map (for runtime population).

pub fn get(&self, key: &str) -> Option<&Value>

Raw getter — returns Option for presence checks.

pub fn is_set(&self, key: &str) -> bool

Check if a key is present in the context.

pub fn get_string(&self, key: &str) -> String

Typed getter — panics if key absent (matches graph-ts behavior).

pub fn get_bytes(&self, key: &str) -> Vec<u8>

pub fn get_big_int(&self, key: &str) -> BigInt

pub fn get_i32(&self, key: &str) -> i32

pub fn get_boolean(&self, key: &str) -> bool

pub fn set_string(&mut self, key: &str, value: impl Into<String>)

Typed setters — for constructing context before createWithContext.

pub fn set_bytes(&mut self, key: &str, value: Vec<u8>)

pub fn set_big_int(&mut self, key: &str, value: BigInt)

pub fn set_i32(&mut self, key: &str, value: i32)

pub fn set_boolean(&mut self, key: &str, value: bool)

pub fn into_fields(self) -> HashMap<String, Value>

Access the underlying fields (for runtime conversion).

Trait Implementations

fn clone(&self) -> DataSourceContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataSourceContext

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

Formats the value using the given formatter.
