Enum RecipeStep 

#[non_exhaustive]
pub enum RecipeStep {
    GasStabilize,
    MainEtch,
    Deposition,
    OverEtch,
    Seasoning,
    Other(String),
}

Canonical set of recipe steps recognised by the DSFB engine.

Fabs that use non-standard step names should map their internal identifiers to the closest canonical variant via RecipeStep::from_str.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

GasStabilize

Pre-etch gas stabilisation — MFC setpoints ramp; relaxed tolerances apply because transient overshoots are physically expected.

MainEtch

Main active etch — tight tolerances; this is the yield-critical window.

Deposition

Deposition step — moderate tolerances.

OverEtch

Post-etch over-etch — slightly relaxed tolerances.

Seasoning

Chamber conditioning after maintenance — widest tolerances.

Other(String)

Any step not explicitly classified; baseline tolerances apply.

Implementations

impl RecipeStep

pub fn from_str(s: &str) -> Self

Parse a step name string into the canonical variant. Matching is case-insensitive. Unknown names produce RecipeStep::Other.

pub fn display_name(&self) -> &str

Short display name for reporting / traceability manifests.

Trait Implementations

impl Clone for RecipeStep

fn clone(&self) -> RecipeStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecipeStep

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

Formats the value using the given formatter.

impl Default for RecipeStep

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RecipeStep

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RecipeStep

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RecipeStep

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RecipeStep

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for RecipeStep

impl StructuralPartialEq for RecipeStep
