Struct MemoryRequirements 

pub struct MemoryRequirements {
    pub parameter_memory: u64,
    pub activation_memory_per_token: usize,
    pub kv_cache_memory_per_token: usize,
    pub typed_sequence_state: Option<TypedSequenceStateMemory>,
    pub overhead_memory: u64,
}

Memory requirements for model execution. This describes logical model requirements, not measured device allocation or an admission guarantee.

Fields

parameter_memory: u64

Model parameter memory in bytes

activation_memory_per_token: usize

Minimum activation memory per token

kv_cache_memory_per_token: usize

Legacy KV cache bytes per token per layer. Ignored and omitted from serialization when typed_sequence_state supplies complete-model bytes.

typed_sequence_state: Option<TypedSequenceStateMemory>

Exact logical sequence state from a typed model plan. Old wire values without this field retain the legacy per-layer interpretation.

overhead_memory: u64

Additional overhead memory

Implementations

impl MemoryRequirements

pub fn checked_calculate_total_memory( &self, batch_size: usize, sequence_length: usize, num_layers: usize, ) -> Option<u64>

Calculate a logical memory estimate, returning None on arithmetic overflow. Typed sequence state is already summed across all layers.

pub fn calculate_total_memory( &self, batch_size: usize, sequence_length: usize, num_layers: usize, ) -> u64

Calculate a logical memory estimate. Overflow saturates to u64::MAX; callers needing an explicit overflow result can use the checked method.

Trait Implementations

impl Clone for MemoryRequirements

fn clone(&self) -> MemoryRequirements

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryRequirements

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MemoryRequirements

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for MemoryRequirements

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
