Enum SkillMetadataError 

pub enum SkillMetadataError {
    MissingFrontmatter,
    FrontmatterTooLarge {
        size: usize,
        limit: usize,
    },
    InvalidYaml(String),
    MissingField {
        field: &'static str,
    },
}

Errors that can occur while extracting SkillMetadata from a SKILL.md’s YAML frontmatter.

Variants

MissingFrontmatter

The content did not start with a ----delimited YAML frontmatter block.

FrontmatterTooLarge

The extracted frontmatter block exceeded MAX_FRONTMATTER_SIZE.

Fields

size: usize

Actual size of the rejected frontmatter block, in bytes.

limit: usize

Maximum allowed size (MAX_FRONTMATTER_SIZE).

InvalidYaml(String)

The frontmatter block was not valid YAML.

The message is a rendering of the underlying serde_norway error (captured eagerly rather than storing the error type itself, so this crate’s public API is not pinned to a specific serde_norway version) with its line number corrected to be relative to the whole SKILL.md file rather than the extracted frontmatter block — the block starts one line after the file’s opening --- delimiter.

MissingField

A required field was absent, or present but empty, in an otherwise valid frontmatter block.

Fields

field: &'static str

Name of the missing/empty field (e.g. "name", "description").

Trait Implementations

impl Debug for SkillMetadataError

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

Formats the value using the given formatter.

impl Display for SkillMetadataError

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

Formats the value using the given formatter.

impl Error for SkillMetadataError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
