Struct Needs 

#[non_exhaustive]
pub struct Needs {
    pub tools: bool,
    pub structured_output: bool,
    pub prompt_caching: bool,
    pub thinking: bool,
    pub images: bool,
}

What a request needs, as a set of yes or no answers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tools: bool

The request offers tools.

structured_output: bool

The request asks for output matching a schema.

prompt_caching: bool

The request places cache breakpoints.

thinking: bool

The request asks the model to reason.

images: bool

The request carries an image.

Implementations

impl Needs

pub fn unmet_by(self, have: &ModelCapabilities) -> Vec<&'static str>

What this request needs and the model cannot do, by name.

An empty list means the request will be sent as written. A non empty one lists what the provider will silently drop, which is worth knowing before you are billed for a reply that ignored half your request.

Trait Implementations

impl Clone for Needs

fn clone(&self) -> Needs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Needs

impl Debug for Needs

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

Formats the value using the given formatter.

impl Default for Needs

fn default() -> Needs

Returns the “default value” for a type.

impl Eq for Needs

impl PartialEq for Needs

fn eq(&self, other: &Needs) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
