Struct CrateName 

pub struct CrateName(/* private fields */);

Crate name from Cargo.toml

Represents a valid Cargo crate name with validation rules:

• Non-empty
• Starts with ASCII letter (a-z, A-Z)
• Subsequent chars: ASCII alphanumeric, -, or _
• Max 64 characters (crates.io limit)
• No reserved names

Naming Convention

Format	Example	Usage
Cargo name	ryo-mutations	[package] name in Cargo.toml
Module name	ryo_mutations	use ryo_mutations::...

Use to_module_name() to convert (hyphen → underscore).

Implementations

impl CrateName

pub fn new(name: impl Into<String>) -> Result<CrateName, InvalidCrateNameError>

Create a new CrateName with validation

Validation Rules (Cargo naming convention)

• Non-empty
• Starts with ASCII letter (a-z, A-Z)
• Subsequent chars: ASCII alphanumeric, -, or _
• Max 64 characters
• Not a reserved name

pub fn as_str(&self) -> &str

Get as string slice

pub fn to_module_name(&self) -> String

Convert to module name (hyphen → underscore)

Example

let name = CrateName::new("ryo-mutations").unwrap();
assert_eq!(name.to_module_name(), "ryo_mutations");

pub fn into_string(self) -> String

Consume and return the inner string

Trait Implementations

impl AsRef<str> for CrateName

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for CrateName

fn clone(&self) -> CrateName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrateName

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CrateName

fn deserialize<__D>( __deserializer: __D, ) -> Result<CrateName, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CrateName

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

Formats the value using the given formatter.

impl Hash for CrateName

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

where __H: Hasher,

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 CrateName

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CrateName
