Why an ICGEM text could not be parsed into SphericalHarmonicCoefficients(super::SphericalHarmonicCoefficients).

Reading a file adds I/O failures on top; that is IcgemFileError(super::IcgemFileError).

Variants

MissingEndOfHead

end_of_head never appeared.

---

MissingHeader

MissingHeader(&‘static str)

A required header keyword is absent.

---

DuplicateHeader

DuplicateHeader(&‘static str)

A header keyword the parser uses appeared twice.

---

InvalidHeader

InvalidHeader(&‘static str, alloc::string::String)

A header value did not parse (keyword, value).

---

NotAGravityField

NotAGravityField(alloc::string::String)

product_type was present but not gravity_field.

---

UnsupportedNormalization

UnsupportedNormalization(alloc::string::String)

norm was something other than fully_normalized.

---

DegreeUnavailable

requested: usize available: usize

The caller asked for a degree above the file’s max_degree.

---

TimeVariableUnsupported

line: usize kind: alloc::string::String

A time-variable record kind (gfct, trnd, dot, asin, acos).

---

UnknownRecord

line: usize kind: alloc::string::String

A data record kind this parser does not know.

---

MalformedRecord

line: usize reason: alloc::string::String

A gfc record with the wrong number of columns or an unparsable field.

---

IndexOutOfRange

line: usize degree: usize order: usize

n > max_degree or m > n.

---

DuplicateCoefficient

line: usize degree: usize order: usize

The same (n, m) appeared twice.

---

NonFiniteCoefficient

line: usize degree: usize order: usize

A coefficient value was NaN or infinite.

---

UnexpectedC00

UnexpectedC00(f64)

C̄00 was present and not 1 (the point-mass term is modelled separately).

---

NonZeroDegreeOne

degree: usize order: usize

A degree-1 coefficient was non-zero: that encodes an offset between the coordinate origin and the centre of mass, which this evaluator does not model (it starts at degree 2).

---

MissingCoefficient

degree: usize order: usize

A coefficient with 2 ≤ n ≤ max_degree never appeared.
