Implementations

impl StandardDefinition

pub fn should_write_large_tool_responses_to_fs(&self) -> bool

Trait Implementations

impl Clone for StandardDefinition

fn clone(&self) -> StandardDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StandardDefinition

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

Formats the value using the given formatter.

impl Default for StandardDefinition

fn default() -> StandardDefinition

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StandardDefinition

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
