Implementations

impl DockerfileElementType

pub fn is_instruction(&self) -> bool

Returns true if this element type is a Dockerfile instruction.

pub fn is_trivia(&self) -> bool

Returns true if this element type is a trivia element (whitespace, newline, or comment).

Trait Implementations

impl Clone for DockerfileElementType

fn clone(&self) -> DockerfileElementType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DockerfileElementType

impl Debug for DockerfileElementType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DockerfileElementType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl ElementType for DockerfileElementType

type Role = UniversalElementRole

The associated role type for this element kind.

fn role(&self) -> Self::Role

Returns the general syntactic role of this element.

fn is_role(&self, role: Self::Role) -> bool

Returns true if this element matches the specified language-specific role.

fn is_universal(&self, role: UniversalElementRole) -> bool

Returns true if this element matches the specified universal role.

fn is_root(&self) -> bool

Returns true if this element represents the root of the parsed tree.

fn is_error(&self) -> bool

Returns true if this element represents an error condition.

impl Eq for DockerfileElementType

impl From<DockerfileTokenType> for DockerfileElementType

fn from(token: DockerfileTokenType) -> Self

Converts to this type from the input type.

impl Hash for DockerfileElementType

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 DockerfileElementType

fn eq(&self, other: &DockerfileElementType) -> 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 DockerfileElementType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for DockerfileElementType
